从火控雷达反对抗的迫切需求出发,以信号截获理论为基础,建立了火控雷达间歇辐射信号模型;基于描述信号截获过程的窗口函数理论,分析得出了火控雷达间歇辐射的截获概率模型;设定典型的仿真参数,且间歇辐射条件下截获概率随间歇周期的变化情况进行了仿真。仿真和分析结果表明,利用截获概率模型可以定量地描述间歇辐射信号的隐蔽性,且间歇周期直接影响信号的低截获性。

A fire-control radar intermission radiation model is estabilised based on signal intercept and capture theory,for meeting the exigent demand of fire-control radars electronic counter-countermeasures(ECCM).Based on window function theory,the intercept probability model of intermission radiation for fire-control radar is obtained after advanced analyzing.Under enactment simulation condition,the movement of intercept probability for intermission radiation along with the change of intermission periodic is simul...
