雷达侦察设备对脉内调频信号分选识别方法探讨

Study of The Sorting and Identification Methods for Radar Reconnaissance Devices to Intra-pulse FM Signal

目前雷达侦察设备对脉内调频的雷达信号只能进行简单的分选,无法识别其脉内的调制类型及调制带宽,从而就无法引导干扰机选择合适的干扰带宽进行干扰。采用对脉冲信号进行多次频率测量的方法,把测量频率存储下来,进行频率调制识别,从而完成脉内调制信号的正确分选,引导干扰机采用合适的带宽进行干扰。

At present the radar reconnaissance device only can sort the intra-pulse frequency modulation（FM） signals simply,can＇t identify the modulation type and modulation bandwidth of the intra-pulse signals,thereby can＇t guide the jammer to select the appropriate jamming bandwidth for jamming.This paper adopts the method to measure the frequency of pulse signal many times,in order to memory the measured frequencies for modulating and identifying the frequencies,thereby finishes the correct sorting to the intra-pulse modulation signals,guides the jammer to select appropriate bandwidth to perform jamming.
