摘要
多输入多输出雷达，利用多个发射天线同时发射不同波形的信号，以获得更多的自由度和角度分集增益，从而有效克服目标RCS闪烁，改善雷达在目标探测、多目标分辨以及参数估计方面的性能。通过对发射波形的优化设计，还能够根据实际应用场景灵活形成期望的发射方向图。本文综述性的介绍了MIMO雷达的起源、发展过程、发展现状、主要类型、主要特点，以及MIMO雷达的主要研究方向、研究机构及其研究成果。
As a new type of radar, multiple-input multiple-output （MIMO） radar exploits multiple transmit-antennas which transmit different waveforms to obtain more degrees of freedom and angular diversity gain and hence combat target radar cross section （RCS） scintillation and improve radar performance in target detection, multiple targets identifiably and parameters estimation The desired transmit beam pattern can be formed much more flexibly by optimization of the transmitted waveform according to actual application. This paper provides a general introduction to the origin, development, current state, dominant types and characteristics of MIMO radar as well as the main research directions, the research institutes and their works
