摘要
通过建立单脉冲雷达导引头角跟踪回路模型,分析了同步闪烁干扰对单脉冲导引头角度、目标视线角速度测量的影响,研究了同步闪烁干扰对单脉冲雷达导引头角跟踪回路的作用机理.通过对同步闪烁干扰信号和角跟踪回路各组成部分带宽的分析比较,研究了闪烁干扰信号对角跟踪回路环节的作用实质.通过仿真验证了选取不同闪烁频率对角跟踪回路的影响效果,为同步闪烁干扰中闪烁频率的选取提供参考.
As blinking jamming has been proven to be an effective countermeasure against monopulse seeker. It is necessary to study the mechanism of the effect of blinking jamming on monopulse seeker. Based on the angle tracking circuit model, influence of blinking jamming upon the angle measure and angle velocity measure of monopulse seeker is studied. Bandwidth of blinking jamming and each part of angle tracking system is analyzed, and the effect of blinking jamming on an angle tracking circuit is studied. The effect of different blinking frequency on the angle tracking system is simulated and evaluated to provide a guideline for the selection of blinking frequency.
