| 摘 要： | 对多输入多输出(multiple input multiple output, MIMO)雷达发射部分相关波形时,比幅单脉冲方法的角度测量性能进行了理论分析。通过建立MIMO雷达的一般信号模型,采用矩阵微分的方法对噪声引起的比幅单脉冲左右波束输出信号的起伏进行了统计分析,从而给出了部分相关MIMO雷达体制下比幅单脉冲方法的理论测角性能。由得出的结论可以直接得出正交MIMO雷达及相控阵雷达体制下比幅单脉冲方法的理论测角性能。通过数值仿真实验对部分相关MIMO雷达下比幅单脉冲方法的性能进行了仿真分析,并验证了理论分析的正确性。

| Abstract: | When the partially correlated waveforms are transmitted by multiple input multiple output (MIMO) radar, the performance of the amplitude comparison mono-pulse (ACM) method is analyzed theoretically. By establishing the signal model of the general signal model of MIMO radar, the fluctuation of the left and right beam, which is caused by the noise, is analyzed statistically by adopting the matrix differential technique, and the corresponding theoretical performance of the ACM method is derived. Moreover, the theoretical angle estimation performance of the ACM method in the orthogonal MIMO and the phased array radar can be obtained directly from the derived result. The performance of the ACM method is verified through numerical experiments. |
