摘　　要：利用雷达侦察信号幅度信息相邻的准确性,提出一种势差算法,并与扩展Kalman滤波算法相结合,提出一种基于扩展Kalman滤波的势差分选算法。该算法通过扩展Kalman滤波平滑脉冲包络,通过势差算法分选雷达信号。测试结果表明,该算法对于复杂体制的雷达信号有较好的分选效果。Based on the accuracy of the amplitudes of adjacent signals, a potential difference sorting algorithm based on the extended Kalman filtering is presented. The extended Kalman filtering is applied to smooth the pulse envelope, and the potential difference algorithm is used to make the radar signal sorting. The test results indicate that the algorithm has a better effect on radar signal sorting with complex system.
