摘　　要：一发多收MIMO雷达结合了集中式和分布式MIMO雷达的工作特点,兼有两种模式的性能优势。接收站可以独立测得发射站角度信息,存在信息冗余,通过加权最小二乘融合可得到高精度的定位结果,这将会使目标关联的结果更加精确。基于T/R-R模式一发双收MIMO雷达,分析了MIMO雷达目标关联的性能,建立了概率模型,推算了正确关联概率和错误关联概率,数值计算和蒙特卡洛仿真结果显示了模型的正确性。最后通过与普通相控阵雷达比较,验证了一发多收MIMO雷达目标关联的性能优势。MIMO radar with single transmitting station and multiple receiving stations combines the features and the performance advantages of centralized and distributed MIMO radars.By transmitting orthogonal signals,the angle information of transmitting station can be measured from receiving arrays independently.Thus information redundancy appears and high localization precision can be obtained with weighted least square fusion algorithm.The improvement of localization accuracy is bound to have positive effects on target correlation.The target association performance of the MIMO radar of T/R-R model is analysed.The probability model is established to calculate the correct association probability and error probability.Then the results of numerical computation and the Monte Carlo simulation show the validity of the model.At last,the association performance advantages of MIMO radar are verified by comparing with the conventional phased array radar.
