摘要：

针对多输入多输出(multiple input multiple output, MIMO)雷达的自由度特性，提出了一种单基地L型阵列MIMO雷达的空间多目标分辨和定位方案和基于Capon波束形成器的MIMOCapon二维空间谱估计方法。该方法可对空间目标二维DOA进行估计从而完成对多目标的分辨定位,对方案中可分辨定位目标数目进行了分析。分析和仿真结果表明，将该方案应用于雷达目标定位系统中，在实际阵元数目不变的情况下，可提高系统自由度的利用率，增加可分辨目标数目，节约成本。

Abstract:

Aiming at the characteristic of degree of freedom in multiple input multiple output (MIMO) radars, a scheme for multitarget identification and localization using a monostatic MIMO radar system with L-shape arrays is proposed, as well as the MIMO-Capon method based on Capon waveformer is presented. Multi-target angles and locations can be distinguished by the MIMO-Capon method. The number of targets that can be uniquely identified with many virtual sensors obtained by proposed scheme is also analyzed. Simulation results show that the proposed scheme enhances the utilization rate of the degree freedom of the system, increases the number of identifiable targets, and saves on cost.
