摘　　要：MIMO雷达是目前正处在快速发展的新概念雷达系统,在定位精度、对低速运动目标的检测、空间分辨率,以及对付隐形目标和低截获概率等方面具有传统雷达不可比拟的优势,其发展现状和需要研究的问题值得关注。从分类、特性、优点等多个方面对MIMO雷达的特点与问题进行分析,重点研究了集中(相干)MIMO雷达和宽域分布MIMO雷达各自的优点和存在的不足,并展望了进一步研究方向。MIMO radar is a kind of new concept radar which is rapidly developing currently. It has the advantages in the aspects of location accuracy, detection of low speed targets, space distinguishing, dealing with invisible targets and low probability of intercept targets etc. , which are better than those of traditional radar. Its development and main problems at present worth our attention. From the classification, characteristics, advantages, and the problem that exists etc. , the characteristics and problem of the MIMO radar are analyzed. The weakness and strength of the concentrated （coherent） MIMO radar and widely distributed MIMO radar are introduced respectively and the future research direction is put forward.
