| 摘 要： | 对MIMO雷达提出了一项新技术——相控阵-MIMO雷达。该技术充分利用了MIMO雷达和相控阵雷达相干处理的优点，其实质就是把发射天线分隔成多个子阵，每个子阵发射相互正交的波形，通过设计每个子阵的加权矢量使天线在空间形成波束，并且每个子阵可以构成MIMO雷达模型。仿真分析表明：和相控阵和MIMO雷达相比，提出的相控阵．MIMO雷达具有更优越的性能。

| Abstract: | The technology of Phased-MIMO radar, which makes most of the advantages of the coherent processing in MIMO and phased-array radars, is presented and its essence is to divide the transmitting antenna into a number of subarrays, from which mutually orthogonal waveforms are transmitted. The weighting vector of each subarray is designed to enable the antenna to form beams in the space, and each subarray can form a MIMO radar model. The simulation results show that the Phased-MIMO radars proposed are superior to MIMO and phased-array radars in performances. |
