MIMO雷达作为一种新体制雷达，具有诸多优点和广泛的应用领域，引起了国内外军事界和学术界的极大关注。空时自适应处理(STAP)主要目的为抑制地杂波，进行地面动目标显示(GMTI)。如今，这项技术又被进一步推广到MIMO雷达系统中，MIMO雷达STAP迅速成为国际雷达界的一个研究热点。该文详细阐述了MIMO- STAP的引入及重要意义，对杂波建模、杂波自由度(DOF)分析、降维(秩)处理、有源干扰与杂波的同时抑制、非均匀杂波环境处理等方面主要研究情况进行综述，并对未来MIMO-STAP技术的发展方向进行了展望。

Multiple-Input Multiple-Output (MIMO) radar is an emerging radar system that is of great interest to military and academic organizations due to its advantages and extensive applications. The main purpose of Space-Time Adaptive Processing (STAP) is to suppress ground clutter and realize Ground Moving Target Indication (GMTI). Nowadays, STAP technology has been extended to MIMO radar systems, and MIMO radar STAP has quickly become a hot research topic in international radar fields. This paper provides a detailed description of the extension and significant meaning of MIMO-STAP, and gives an overview of the current research status of clutter modeling, analysis of clutter Degree Of Freedom (DOF), reduced-dimension (reduced-rank) processing, simultaneous suppression of clutter plus jamming, non-homogeneous environment processing, and so on. The future perspective for the development of MIMO-STAP technology is also discussed.
