摘　　要：多站无源定位系统中,信号到达两个观测站的时间差信息可用于分选和定位。提出一种改进的二维时差直方图脉冲分选配对方法。该方法采用聚类算法动态确定直方图中心,改进扩展直方图构建方案,在较好解决时差直方图及其衍生算法中存在的直方格分裂问题,直方图噪声引起的脉冲漏分选问题的同时,同步实现信号分选和时差配对。仿真结果验证该算法的有效性。In the multi-station passive location system,the time difference of arrival can be used for pulse sorting and location.An improved pulse sorting matching method based on two-dimensional TDOA histogram is proposed.Clustering algorithm is adopted to determine the histogram center dynamically,and the extended histogram construction scheme is improved.The problems of splitting histogram and pulse missing caused by histogram noise in TDOA histogram and its derivative algorithm are solved.Signal sorting and TDOA matching are realized simultaneously.Simulation results show the effectiveness of this method.
