摘要
多输入多输出(MIMO)雷达是最近所提出的一种新型的雷达体制。通过利用空间分集和角度分集,从而避免了雷达目标的多径衰落问题。这里主要分析了MIMO雷达基于似然比的检测性能。另外,这里也将MIMO雷达跟相控阵雷达的检测性能做了对比,仿真结果表明MIMO雷达相比传统雷达具有的优异的检测性能。
Multiple Input-Multiple Output （MIMO） radar is the recent emergence of a new radar technology. By using spatial diversity and angel diversity to avoid multipath fading. In this paper, we mainly analysed the detection performance of MIMO radar based on criteria of likelihood ratio. In addition, its detection performance is compared with phased array radar under the same condition. The simulation result shows that MIMO radar has a good detection performance compared with phased array radar.
