摘要：

从火控雷达抗电子侦察的需求出发,研究通过组网技术降低雷达信号截获概率的方法。首先分析雷达侦察系统的前端截获概率以及影响雷达截获的因素,在此基础上,介绍基于交替间歇辐射的火控雷达组网理论,提出脉冲间隔自适应变化的辐射信号模型,并利用窗口函数对组网条件下的截获概率进行研究;最后设定参数,对三部火控雷达组网的效果进行仿真。实验结果证明:利用火控雷达组网的方法可以降低信号的截获概率,延长信号被反辐射武器截获的时间,从而获得良好的作战效能。

Abstract: In order to antagonize electronic support measurement, a method to decrease the intercept probability of fire control radar signal based on radar netting was researched. First, the front-end intercept probability of radar reconnaissance system was analyzed, as well as the factors that affect the intercept probability. On this basis, the fire control radar network theory was introduced and a new signal model of adaptive pulse interval was proposed. Intercept probability was studied using window function on the condition of radar network. Then, the effect of three-fire control radar network was simulated. Results show that the use of fire control radar network is good at reducing the intercept probability of radar signals effectively, extending the time of the signal being intercepted by anti-radiation weapons with good operational performance.

Keywords: fire control radar; low probability of intercept; window function; radar network
