基于联合概率分布的激光有源干扰效果分析

Analysis of Laser Active Jamming Effect Based on Union Probability Distribution

在综合考虑导引头波门、制导激光时间稳定度、干扰激光时间稳定度、干扰激光光程差的时间修正量等因素的基础上,根据制导激光概率密度函数和干扰激光概率密度函数,推导出制导激光与干扰激光的联合概率密度函数,建立了干扰激光超前于制导激光进入导引头波门的概率模型,并通过仿真实验分析得出最优超前时间量的范围。

On the basis of considering factors such as the gate of seeker,time stability of guidance and jam ming laser,time correction of jamming laser optical path difference synthetically and probability density func tions of guidance and jamming laser,the union probability density functions of guidance and jamming laser are derived.A probability model for jamming laser entering the gate of seeker ahead of guidance laser is built.Through simulation experiment analysis,optimum leading time range is got.
