| 摘 要： | 针对“宽波束发射一宽波束接收”多基地雷达存在定位精度低和易产生虚假目标等缺点，讨论了一种空间接收分集的多入多出( MIMO)雷达，该MIMO雷达是一种特殊结构的一发（射站）多（接）收（站）( STMR)多基地雷达，其工作模式也为“宽波束发射一宽波束接收”，能避免复杂的波束同步扫描问题。对接收分集MIMO雷达提出了一种基于Capon谱估计的多目标定位方法，并与普通STMR多基地雷达的定位精度进行了比较。仿真结果表明，接收分集MIMO雷达能有效解决“宽波束发射一宽波束接收”多基地雷达的低定位精度和易产生虚假目标的问题。

| Abstract: | Aiming at the disadvantages of low positioning accuracy and target ghost generation in multistatic radar with broad transmitting beam and broad receiving beam, multiple input multiple output(MIMO) radar based on receiving diversity was discussed.The MIMO radar is a special structure of single transmitting station and multiple receiving stations(STMR)-multistatic radar with broad transmitting beam and broad receiving beam, and can avoid the complicated beam scan synchronization.A scheme for multi-target loca... |
