Firstly, the obtained radar signal radio frequency, pulse width, repeat frequency are composed to get a combined probability assignment function of radar parameters by applying D-S method.
首先，对侦察雷达所能探测到的目标雷达信号的载频、脉宽、重频，应用证据理论将其组合，得到雷达参数的联合概率分配函数。
The amplitude of wave before repeat wave and dicrotic wave obviously increased compared with vire pulse(P<0.01), but its width of main wave didn't increase greatly(P<0.01).
与弦脉比较，紧脉重搏前波波幅及降中波波幅增高明显（P＜0.01）；而主波宽度不如弦脉增加明显（P＜0.01）。
