摘　　要：通过对小波变换法、Wigner-Ville分布等典型雷达信号脉内特征提取方法优缺点的分析,提出了一种将小波变换法和Wigner-Ville分布提取的结果进行截断综合的综合提取算法,实现了雷达信号的脉内特征准确提取。仿真结果表明,该算法在较低信噪比下仍有很好的效果。Some typical methods of extracting the in-pulse features of radar signal such as wavelet transformation and WVD were compared. Then a new method based on the colligation of wavelet transformation and WVD which could extract in-pulse features from radar signal in low SNR exactly was presented. The result of the simulation experiments provedthe feasibility of this method.
