摘　　要：当敌方反舰导弹攻击我方舰艇时,我方可实施冲淡干扰进行防御,其干扰时机对干扰效果起着决定性作用。对此,提出一种基于时空域限定条件的冲淡干扰发射时机模型,首先建立舰艇、箔条云、导弹运动模型,然后根据导弹末制导雷达开机时间得到时域限定范围,根据末制导雷达搜索波束角与箔条云、箔条云与舰艇位置关系得到空域限定范围,通过模型计算箔条云距雷达搜索波束角边界距离、干扰有效时机范围和补射箔条弹策略。仿真结果表明,新模型可以较好地确定冲淡干扰发射时机,相关结论对冲淡干扰的运用和效果评估有重要指导价值。When the enemy’s anti-ship missile attacks our ship,the dilution jamming can be implemented for defense.Dilution jamming timing plays an important role in jamming effect.Therefore,a timing model of diluting jamming based on time-space constraints is proposed.Firstly,models of ship,chaff cloud and missile movement are established.Secondly,the limitation of time domain is obtained according to the booting time of missile terminal guidance radar.Then,according to the relationship between searching beam angle and chaff cloud,chaff cloud and ship position,the limited range of spatial position is obtained.Finally,the model is used to calculate the distance from the chaff cloud to the radar search beam angle boundary,the range of jamming effective timing and the strategy of supplementary chaff shot.Simulation results show that the new model can be used to determine the launching time of dilution jamming,and it has an important guiding value for the application and effect evaluation of dilution jamming.
