摘要
针对箔条走廊对雷达压制性干扰的作战效能问题,从箔条干扰的军事经济效益角度出发,建立了基于雷达发现概率的干扰效费比模型,提出了箔条压制性干扰取得最大军事经济效益的方法,通过实例仿真证明了该方法的有效性。同时,基于箔条云对电磁波的衰减特性建立了雷达作用距离衰减方程,推导出箔条走廊对雷达干扰的压制系数计算方法,得到压制系数的选取与被干扰雷达的极化方式无关,而只与被掩护的攻击机的雷达有效反射面积有关的结论。
Aiming at the blanket jamming operation effectiveness of chaff corridor to radar,from the aspect of military economy benefit of the chaff jamming, this paper sets up the model of benefit cost ratio of jamming based on radar detection probability, brings forward the method of chaff blanket jamming achieving the maximal military economy benefit, and proves that this method is effective by practical examination simulation;at the same time, based on the attenuation characteristic of electromagnetism wave passing through chaff cloud,this paper establishes the attenuation equation of radar range, educes the method to calculate the suppressing coefficient of chaff corridor jamming radars,concludes that the choice of suppressing coefficient is only correlative to the RCS of covered attacker but to the polarization mode of the jammed radar.
