摘　　要：本文针对不同的目标模型对分布式MIMO雷达工作模式进行了相干处理和非相干处理的分类,推导出参数估计器与目标检测概率的最终表达式,论证了不同的布站方式以及收发站数对参数估计和目标检测性能的影响,支撑了分布式MIMO雷达相关理论的研究。仿真表明布站方式会较大影响参数估计与复杂目标检测的精度,并与传统相控阵雷达进行对比,证明了文章结论的有效性。Corresponding MIMO radar signal models are established according to the modality of signal processing in parameter estimation and detection, based on which the working patterns of MIMO radar can be classified as coherent processing and non-coherent processing. On this foundation, the performances of estimation and detection are analyzed in detail, primarily focusing on the difference of two models, which support the conclusion of the rule for configuring transmitters and receiver is provided based on the analysis of effect to performance. The simulation results show the effectiveness of the proposed algorithms by quantitatively analyzing the main factors affecting the capability of forensics.
