在相控阵雷达中采用序列检测可提高雷达信号检测性能和改善数据库，本文利用雷达极化信息对三种典型序列检测方法进行了改进研究。并对这三种改进算法在相控阵雷达中的应用性能作了详细的分析，同时进行了相干视频仿真实验。仿真结果表明：极化信息的利用使雷达搜索目标能力得到明显改善，同时双幅度门限检测法的应用使相控阵雷达的检测性能更加优越。

Sequential detection can improve the target detection performance and the data rate in phased array radar. In this paper, three kinds of typical sequential detection methods are presented and modified based on radar polarization information, and the performances of these three modified methods in phased array radar are analyzed in details. Then coherent video simulation is carried out. The results show that exploitation of polarization information enhances the surveillance capability of phased array radar. Meanwhile, the use double amplitude threshold detection algorithm leads to much better performance of array radar.
