摘　　要：研究分析了HPM信号的包络相位等特征,得知其包络不规整而且相位存在抖动,故采用高斯多峰模型拟合其包络,多项式模型拟合其相位,结合包络与相位的拟合模型获得了HPM信号的脉冲调制模型,最后在Matlab中利用该重构方法对多个HPM信号进行重构,均获得了较小残差的重构信号,检验得知该方法能够对HPM短脉冲雷达发射信号实现准确有效的信号重构。The high-power microwave (HPM) short pulse radar uses high power microwave as transmitting signal,which doesn't work well with the model of the conventional radar transmitting signal.This paper analyses the characteristics of HPM signal,and finds that it has irregular envelope and jittery phase.Therefore,we fit its envelope by Gauss multi-peak model and its phase by polynomial model.We obtain its pulse modulation model,and verify the method of reconstruction with small residual by Matlab.Our study is significant to the simulation of this new kind of radar.
