摘要
多输入多输出（MIMO）雷达是近年来出现的一项新的雷达技术．论文在对MIMO雷达概念和发展过程作了简单描述后，首先对基于发射分集的MIMO雷达系统原理作了详细介绍，分析了其在抗雷达信号截获、强杂波中弱目标检测、低速目标检测等方面的性能改善，指出了其可能的应用方向．论文接下来对收发全分集的MIMO雷达构成原理进行了讨论，给出了目前已取得的初步理论结果和仿真实验结果，说明了其在目标检测、目标参数估计、目标识别和分辨等方面具有的良好性能．论文最后对两种MIMO雷达体制进行了分析比较，讨论了二者的特点和目前的可实现性，指出了待解决的理论问题和实现中的技术问题．
Multiple Input Multiple Output （MIMO） radar is a new radar technique developed recently. After a brief description of MIMO radar concept and its development, the MIMO radar system based on only transmitting diversity is introduced in detail, firstly. Its performance improvements are analyzed in the ways such as anti-nterception of radar signal, weak target detection in strong clutter, and low velocity target detection, and its potential applications are pointed out too. Then,the principle of MIMO radar based on both transmitting and receiving diversities is discussed, some preliminary analyses and simulation results are presented,the good performances in target detection, parameter estimation,and target resolution are described also. Finally,by comparing the two MIMO radars given above,their characteristics and implementations are analyzed. As well ,the theoretical problems and implementation techniques to be solved are pointed out.
