| 摘 要： | 给出MIMO雷达在距离-多普勒2维分辨单元处理和距离1维分辨单元处理情况下的信号模型。根据这两个信号模型各自的特点,分别构造信号的相关矩阵,将信息论准则和盖式圆准则应用于MIMO目标数量估计之中。仿真结果表明在白噪声情况下,信息论和盖式圆准则均可有效估计目标数量;在色噪声情况下,盖式圆准则可有效估计目标数量。

| Abstract: | The signal models of MIMO radar are described in both range-Doppler two dimensions processing and range one dimension processing situations.The correlation matrixes are constructed based on the characters of the signal models,and then the information theory and Gerschgorin disks criteria are used in the target number estimation for MIMO radar.Simulation results suggest that the information theory and Gerschgorin disks criteria are available in white noise,and the Gerschgorin disks criterion is effective in colored noise. |
