摘要 MIMO雷达采用了空间分集与信号分集技术,与传统相控阵体制雷达相比,可望获得更高的目标检测性能.针对杂波与噪声同时存在的实际背景,建立了MIMO雷达检测模型,导出了检测性能的理论公式,并与传统相控阵雷达进行了仿真比较分析.理论与仿真结果表明,当信噪比大于等于10dB时,MIMO雷达的检测性能要明显优于相控阵雷达. Compared with the conventional phased array radar, MIMO radar may acquire a better target detection performance by exploiting space diversity and signal diversity techniques. Aimed at the real background of both clutter and noise, the detection model of the MIMO radar was set up, the theoretical formula of detection performance was given, and the detection performance was simulated and analysed by comparison with the conventional phased array radar. The theory and simulation results show that the MIMO radar detection performance obviously outperforms the phased array radar＇s when signal-to-noise ratio （SNR） is not less than 10 dB.
