摘　　要：基于最佳检测准则,提出了一种新的雷达发射-接收极化联合优化方法。首先,建立了全极化雷达目标回波模型,设计了基于纽曼-皮尔逊(Neyman-Pearson)准则的雷达目标全极化检测算法,推导分析了检测性能;其次,提出了雷达发射-接收极化的联合优化方法,提高了雷达目标的检测性能;最后,仿真试验结果表明,本算法能够显著提高雷达目标的检测性能。In this paper,a new joint radar transmitter and receiver polarization optimization method is proposed based on the optimal detection criterion.First,a fully-polarimetric radar echo model is introduced,and the fully-polarimetric target detection algorithm is designed based on Neyman Pearson criterion,the detection performance is derived and analyzed.Then,a joint radar transmitter and receiver polarization optimization method is proposed to improve the capability of the target detection.Finally,the simulation results demonstrate that the target detection performance can be improved by using this algorithm remarkably.
