摘　　要：航空兵在执行对地突防任务的过程中,电子干扰是掩护突防编队、提高突防飞机生存概率的重要手段。提出一种利用箔条云团散射远距干扰信号对地空导弹制导雷达进行干扰的复合干扰方法。该方法使用干扰机照射突防航线上布撒的箔条云团,通过箔条云团的散射,从地空导弹制导雷达的主瓣注入干扰能量;在此基础上,建立实施正面突防时的箔条弹多次抛洒模型,该模型可以有效的计算出突防编队抛洒箔条弹的间隔距离,从而确定抛洒箔条弹的时机,并通过实例分析验证。结果表明:该方法具有更好的干扰效果;箔条弹多次抛洒模型可靠,可以确保对敌地空导弹阵地的持续干扰。Electronic jamming is an important means to protect penetration formation and improve the survival probability of penetration aircraft in the process of air force penetration.A compound jamming method for surface-to-air missile guidance radar using chaff cloud scattering long-range jamming signal is proposed.This me-thod is to use jammers to irradiate chaff clouds scattered on penetration routes,and injects jamming energy from the main lobe of surface-to-air missile guidance radar through the scattering of chaff clouds.On this basis,a multi-time spraying model of chaff bombs in front penetration is established,which can effectively calculate the interval distance of the spraying of chaff bombs in penetration formation.The interval distance is used to determine the time of spraying chaff bombs,which is verified by an example.The results show that this method is of better jamming effect,and the chaff bomb multiple throwing model is reliable,which can ensure the continuous jamming to the enemy surface-to-air missile position.
