【摘要】对电子战中压制式干扰的干扰效能的有效评估问题进行了研究.首先分别利用无干扰状态和干扰状态的雷达探测距离求解了信噪比和信干比的表达式,进而建立了两种不同状态下的探测概率模型.然后通过模拟干扰机的自卫干扰和支援干扰场景,在设置雷达参数和干扰参数后,仿真比较了3种不同RCS的目标在上述两种干扰模式下雷达探测概率的变化.最后对压制干扰效能进行了科学评估.评估结果表明:干扰机的压制干扰能够有效降低雷达探测性能,自卫干扰时,大幅提升自身的安全性;支援干扰时,提高目标机的突防生存力.%The effective evaluation of the jamming effectiveness of the oppressive jamming in the electronic warfare was studied.Firstly,the formulas of signal to noise ratio and signal to jamming ratio were derived respectively by using radar detection distance with jamming condition and without jamming condition,and the detection probability models were established under two different conditions.Then the variations of radar detection probability of three kinds of targets' radar cross section (RCS) were simulated and analyzed by imitating the combat scenarios of self-defense jamming and support jamming and setting radar parameters and jammer parameters.Finally,oppressive jamming effectiveness was evaluated scientifically.The results indicate that oppressive jamming of
