• 1. Waveform design for joint radar-communication system with multi-user based on MIMO radar
  • 基于MIMO雷达的多用户联合雷达通信系统的波形设计
  • 英文摘要
    • The joint radar-communication system integrates the function of detection and data transmission to reduce interference and improve the overall spectrum efficiency, as well as to reduce total volume of devices in vehicles, which is widely used in the intelligent transportation systems. Among these joint systems, a MIMO radar based system has significant advantage for multi users with orthogonal waveforms transmitted by each antenna. In order to realize high speed transmission, a quasi-orthogonal multi-carrier LFM-CPM waveform is proposed for the joint system. This waveform preserves the characteristics of LFM with constant envelope and continuous phase, so that the distortion caused by the nonlinearity of the high power amplifier and the reduction of effective working distance can be avoided. The spectral efficiency of the proposed waveform is much higher than the 1-bit multi-carrier LFM waveform and simulation of bit error rate (BER) performance is close to that of single-carrier LFM-CPM with no interference. The simulation of ambiguity function shows that the random communication symbols has little influence on the radar subsystem. In a word, the shared waveform based on multi-carrier LFM-CPM and MIMO radar can meet the need of the detection and multi-user transmission at the same time, and is suitable for the intelligent transportation systems.

• 2. Low Probability of Intercept-Based Optimal OFDM Waveform Design Strategy for an Integrated Radar and Communications System
  • 雷达通信一体化系统中基于低截获概率的最优正交频分复用波形设计策略
  • 英文摘要
    • The integration of radar and communications systems can provide great advantages, such as enhanced efficiency, structure simplification, less occupied hardware resources, and interference mitigation, compared with traditional individual radar and communications applications. Extensive studies have presented achieving improved system performance, whereas the problem of low probability of intercept (LPI)-based waveform design for the integrated system is seldom discussed in the literature. In this paper, an LPI-based optimal orthogonal frequency multiplexing modulation (OFDM) waveform design strategy is developed for an integrated radar and communications system (IRCS). The dedicated transmitter in this system transmits integrated OFDM waveform for simultaneously target parameter estimation and downlink communications. The basis of the underlying strategy is to employ the optimization technique to design the integrated OFDM waveform of IRCS in order to minimize the total radiated power, while satisfying the specified requirements of target parameter estimation and data information rate. We analytically show that the resulting optimization problem is convex and can be solved by formulating the Karush-Kuhn-Tuckers optimality conditions. Numerical simulation results demonstrate that our proposed strategy can solve the waveform design problem in the IRCS with low complexity, and the LPI performance of the IRCS can efficiently be enhanced by utilizing the proposed integrated OFDM waveform design strategy.

  • 英文摘要
    • Joint radar-communication systems based on integrated waveforms can simultaneously realize high-speed data transmission and target detection in one device, providing information sharing networks and information sources for decision-making of intelligent transportation systems. In this letter, based on a combination of linear frequency modulation (LFM) signals and continuous phase modulation (CPM) signals with an adjustment of communication symbols of length k, an integrated waveform k-LFM-CPM and a complete system framework cascaded with low-density parity-check (LDPC) codes is carried out. With a limited bandwidth, this system achieves a better bit-error rate than original LFM-CPM-LDPC systems, benefiting from an almost non-broadening power spectrum and additional information used in the cascaded decoding process. Finally, through the optimization of the mismatched filter, it is verified that the detection performance of the integrated waveform with accumulation is almost the same as that of the LFM signal.

  • 英文摘要
    • To reduce the consumption of spectrum and hardware resource, two methods are proposed to design the integrated waveform that can satisfy the requirements for both radar and communication. First, a linear superposition (LS) method is proposed to design the transmit waveforms of a uniform linear array (ULA). In the far field of the ULA, the designed transmit waveforms can simultaneously synthesize the desired radar and communication waveforms in different directions. However, the designed waveforms usually have high peak-to-average power ratio (PAPR). Then, an alternative projection (AP) method is proposed to reduce the PAPR of the transmit waveforms. The AP method can devise the waveforms with constant modulus. Both the proposed methods can perform radar and communication function in different directions. Finally, several simulation results are given to verify the effectiveness of the proposed methods.

  • 英文摘要
    • Integration of radar and communication is an important trend in the future development of radar technology. The combination of radar and communication allows them to give full play of their respective superiority while make up for their deficiencies. As a result, the detection radar becomes communication radar, a network platform for information giving, which will immensely enhance the force of battle group. The key of Radar-communication integration is the design of integrated waveform. A practicable waveform is to modulate Minimum Shift Keying (MSK) signal onto Linear Frequency Modulation (LFM) signal, but the problem is the likelihood of leading to the extension of the spectrum, which will seriously affect the performance of radar detection and communication. To solve the problem, this paper will elaborate from the following aspects: 1. Mathematical expression of the integrated waveform in order to deduce the reason of spectrum extension and propose solutions accordingly. 2. Application of MATLAB in the simulation of spectrum extension [1] and result of limiting spectrum extension using the algorithm proposed in this paper. 3. The practicability of the method proposed by in this paper by implementing integrated waveform and algorithm on FPGA using VHDL language.

    • In an integrated radar and communication system, the filter output of each pulse of the integrated radar and communication waveform usually has high sidelobe level (SLL) and signal-to-noise ratio (SNR) loss as well as serious range sidelobe modulation (RSM). To solve these problems, a joint weighted optimization (JWO) method is proposed to design the filters. In this method, the filters for different integrated radar and communication waveforms are designed by jointly minimizing the RSM, SNR loss, and SLL according to different practical demands. In terms of the RSM, SNR loss, and SLL, the performance of the designed filters is tunable by reasonably changing the weight factors. Finally, several numerical results are presented to verify the effectiveness of the proposed method.

• 10. Super-Resolution Range and Velocity Estimations With OFDM Integrated Radar and Communications Waveform
  • OFDM集成雷达和通信波形的超分辨率范围和速度估计
  • 英文摘要
    • In the intelligent transportation system, it is an efficient way for the intelligent vehicle to use the integrated radar and communications system (IRCS) to obtain the range and velocity estimations of other vehicles and simultaneously communicate with other facilities, such as vehicles and base stations. In the IRCS, the transmitted waveform is the orthogonal frequency division multiplexing (OFDM) integrated radar and communications waveform that contains communications information. Due to the existence of communications information, the traditional range and velocity estimation methods in radar can not be directly utilized in the IRCS. Moreover, to improve the resolution of range and velocity estimations, the signal bandwidth and coherent processing interval (CPI) are usually required to be increased, which will result in the increase of system cost and the reduction of update rate. To solve these problems, a auto-paired super-resolution range and velocity estimation method is proposed by using the OFDM integrated radar and communications waveform. First, the communications information in the received signals is compensated. Then, the frequency smoothing is performed to reduce the correlation between the echoes reflected by different targets. Finally, the auto-paired super-resolution range and velocity estimations are obtained by exploiting the translational invariance structure of the underlying signal model in both frequency and pulse domains. Furthermore, Cramér-Rao bounds (CRBs) on range and velocity estimations with the OFDM integrated radar and communications waveform are derived. Several numerical examples are presented to verify the effectiveness of the proposed method.

  • 英文摘要
    • This paper presents cognitive overlapped-frequency diverse array (FDA) for joint radar-communications to achieve improved performance for moving radar target and communica- tion receiver(s). In this scheme, the FDA transmit array is divided into two subarrays and each subarray coherently transmits an orthogonal waveform with different frequency increments. In addition, we consider the time variant in FDA, which is usually ignored in the literature. Further, we propose Chebyshev window function to design two transmit weights matrices to achieve distinct sidelobe levels (SLLs) for communication operation but the same mainlobe for radar functionality. The communication information message is embedded into the orthogonal waveforms via the sidelobe control during each radar pulse. By using the cognitive closed-loop method, we can update the parameters in real time to improve moving target and communication receiver(s) tracking performance. Moreover, the information bits can be efficiently detected by the intended receiver due to equal magnitude in the SLLs. The effectiveness of the proposed scheme is verified by simulation results.

  • 英文摘要
    • As a burgeoning communication technology with flexible resource allocation, high spectral efficiency, strong anti-dual selective fading ability, filter-bank multi-carrier (FBMC) has a good prospect in the development of radar-communication integration. In this paper, we introduced FBMC technology to this integrated system and found many problems as follows (i) in order to transmit information by radar waveform, the integrated signal is loaded with the communication data. Since the data may be duplicated and similar, their correlation is big enough, which led to the radar resolution efficiency decline; (ii) when the data rate of communication increase, the number of FBMC symbols and subcarriers are increased as a consequence. The research shows it introduce a lower amplitude of the clutters of the distance ambiguity function, but the ambiguity area is widened. In order to improve the performance of distance resolution, this paper proposes a m-Sequence filter-bank multi-carrier (MS-FBMC) integrated radar-communication signal by preencoding of communication information based on m-Sequence to improve the radar-communication integration signal autocorrelation. The simulation results show that MS-FBMC signal's ambiguity function has an ideal thumbtack shape, and the distance distinguish capability of FBMC radar is also enhanced without decrease the transmission rate at the same time.

  • 英文摘要
    • Increasing congestion has spurred investigations into more efficient utilization of the radio frequency (RF) spectrum while minimizing the volume and weight of the RF equipment. Considering the similarity of radar and communication in both software and hardware, this paper presents a co-design integrated waveform of radar and communication based on the multiantenna system. In this paper, communication data is first transported by utilizing space-frequency modulation on a fixed transmitting frequency set. By using digital beamforming technology in the subarray level, directional communication with cooperative targets in the main lobe can be achieved. However, modulation in space-frequency domain results in high sidelobes in the autocorrelation function. Thus, to acquire an acceptable radar performance, the mismatched filter (MMF) is proposed to realize information defusion and sidelobe suppression. Aiming at reducing the signal-to-noise ratio loss of the MMF process, the filter response is further modified. Finally, numerical simulations assess the effectiveness of the proposed MMF and the Doppler coherency between pulses for clutter cancellation. Simulation results demonstrate the capability and potential of the proposed co-design signal for radar-communication system.

    • This paper investigates the problem of low probability of intercept-based optimal power allocation (LPI-OPA) for an integrated multistatic radar and communication system, which consists of multiple transmitters operating at different frequencies, a radar receiver, and a communication receiver (CR). The integrated multistatic radar and communication system is capable of fulfilling the requirements of both radar and communication subsystems. The key tenet of the integrated system is to minimize the total power consumption by optimizing the transmit power allocation at each transmitter for radar waveforms and information signals, which is constrained by a predetermined target detection performance for the RR and a desired information rate for the CR. Since the analytical closed-form expression of the probability of detection is not tractable, its upper bound is derived. We analytically show that the resulting optimization problem can be reformulated as two subproblems, which can be solved by an efficient solution procedure based on the approach of linear programming and the Karush-Kuhn-Tuckers optimality conditions. Simulation results are provided to show that the LPI performance of the integrated multistatic radar and communication system can significantly be enhanced by employing our proposed LPI-OPA scheme.

  • 英文摘要
    • Instead of only considering the radar estimation error in the traditional radar system (TRS), for the integrated radar and communication system (IRCS), we investigate the Cramer-Rao bound (CRB) of the localization estimation, which is influenced by both radar estimation error and communication transmission error. The functions of radar and communication are operated simultaneously by embedding the communication symbols into the multicarrier radar waveforms. Firstly, we derive the CRB of time/direction of arrival (TOA/DOA) estimation. To minimize the estimation error, we maximize the signal-to-interference-plus-noise ratio (SINR) of radar by iteratively optimizing the radar transmit and receive beamformers (with the constraint of available transmit power). Then, the CRB of localization estimation is derived using hybrid TOA/DOA measurement. The local CRBs from different IRCSs are fused according to the linear fusion rule at the fusion center (FC). Finally, numerical results demonstrate that the additional estimation errors for the IRCS are mainly determined by the channel conditions of communication and available transmit power; the estimation accuracy for both IRCS and TRS can be improved through the iterative transmit and receive beamforming (ITRB) technique.

    • A joint radar-communication system is an integrated platform which implements radar and communication function simultaneously. This duality provides an effective way to alleviate the problem of increasingly tensive spectrum congestion. In this paper, we consider a dual functional signal designing method for a joint system embedding communication information into radar radiation. Contrary to previous waveform design methods that embed communication symbols on permutations of frequency-hopping (FH) codes, the proposed information-embedding scheme utilizes the FH code selection and phase shift keying (PSK) modulation jointly to accomplish waveform diversity. Benefiting from the joint implementation of frequency modulation and phase modulation within each subpulse, the proposed scheme greatly increases the bandwidth efficiency. Simulation results demonstrate that the proposed information-embedding scheme achieves a high data transmission rate and shows great symbol error performance at the expense of radar performance.

    • In view of the defects that high range side lobes and high peak-to-average power radio (PAPR) in radar and communication integrated systems based on traditional orthogonal frequency division multiplexing (OFDM), a co-designed OFDM waveform based on Golay block coding for joint radar-communication system is proposed in this paper. The communication information is coded into Golay complementary sequences by Reed-Muller codes, which can not only reduce the PAPR of the system, but also can improve the error correction capability. However, the code rate of the algorithm will decrease rapidly with the increase of the number of subcarriers. Furthermore, the traditional block coding would impact on the final superimposed waveform performance due to phase randomness. Hence, a self-disarrange block coding algorithm is proposed. The radar and communication performance of the designed waveform, including wideband ambiguity function, range profile, PAPR, and bit error rate, is analyzed and simulated. The results demonstrate that the PAPR of the waveform and BER can be reduced effectively, while the range side lobes can be decreased for better radar detection performance.

    • Existing studies on joint radar and communication systems are mainly based on a common assumption: Gaussian environment. Nevertheless, this does not hold in many complicated scenarios. In this letter, mutual information (MI)-based waveform design method for the integrated orthogonal frequency division multiplexing radar-communication system in Gaussian mixture (GM) clutter is investigated. First, from the statistical perspective, the approximate differential entropy of received signal in GM clutter is derived. Subsequently, an adaptive waveform design method is proposed by maximizing the MI, subject to three metrics: communication channel capacity; subcarrier power ratio; and energy constraint.

  • 基于OCDM的雷达通信信号的PAPR降低方法
  • 英文摘要
    • Waveform design for joint radar-communication system plays an important role in recent years. In this paper, we present an integrated radar and communication signal based on the orthogonal chirp division multiplexing (OCDM) signal which embeds communication data in each mutually orthogonal chirp radar signal. Furthermore, a novel approach is proposed to reduce peak-to-average power ratio (PAPR) of the joint signal. Part of the chirp tones are used to embed communication information, while the other tones are used merely to generate the peak canceling signal. Without extra spectrum occupy in conventional tone reservation (TR), the proposed method can make full use of spectrum resources. Simulation results show that the proposed method can efficiently reduce PAPR of the joint signal with decent radar and communication performance.

    • 近年来，联合雷达通信系统的波形设计发挥了重要作用。在本文中，我们提出了一种基于正交线性调频分割复用（OCDM）信号的集成雷达和通信信号，该信号将通信数据嵌入每个相互正交的线性调频雷达信号中。此外，提出了一种新颖的方法来降低联合信号的峰均功率比（PAPR）。线性调频音的一部分用于嵌入通信信息，而其他音调仅用于生成峰值消除信号。无需额外的频谱占用常规音调预留（TR），该方法可以充分利用频谱资源。仿真结果表明，所提出的方法可以有效降低联合雷达信号的PAPR，并具有良好的通信性能。
