在考虑地对空干扰作用和机载武器可攻击区域制约的基础上,首先将攻击机进入目标过程分解成目标落入机载雷达有效作用区域、飞机完成攻击准备这两个基本事件。然后建立了电子干扰条件下目标暴露区、攻击机侧向偏离目标距离、机载武器可攻击区近界和进入目标概率等计算模型。最后通过算例对模型中的主要因素进行了分析验证,得出了干扰功率谱密度对攻击机进入目标概率的影响曲线。

Based on comprehensive consideration of the constraint conditions including surface-to air interference and airborne weap-on attack regions, firstly the process that attack aircraft running in target was decomposed into two basic events, including ground target situating in active region of airborne radar, attack aircraft finding the target and preparing for the attack. Then the target ex-posed region calculation model under electronic interference, the side direction deviating distance model of attack aircraft, near boundary calculation model of airborne weapon attack regions and run-in target probability calculation model were established. Through an example, the main factors of model were analyzed. Finally, the curve charts of jamming power spectral density's effect on probability of run in target for attack aircraft were obtained.
