摘要
针对频率步进毫米波精确制导武器如何实施有效对抗问题,在分析频率步进毫米波导引头二维成像工作原理基础上,构建了导引头二维成像场景,对频率步进毫米波导引头成像处理以及多种干扰样式进行了系统全面仿真。仿真结果表明,不论干扰源是否位于导引头天线波束覆盖范围内,采用非相参干扰和相参干扰都可对毫米波导引头实现干扰,非相参干扰能量较为分散,相参干扰能量较为集中。据此,提出了逆增益和有源干扰的复合干扰策略,在实现频步进毫米波导引头干扰的同时,可同步实现干扰源自身防护。
Aiming at the problem of how to implement effective countermeasures against frequency-stepping millimeter-wave precision guided weapons,this paper analyzes the working principle of two-dimensional imaging of frequency-stepping millimeter-wave guided seekers,constructs the two-dimensional imaging scene of frequency-stepping millimeter-wave guided seekers,and carries out systematic and comprehensive simulation on imaging processing of frequency-stepping millimeter-wave guided seekers and various jamming techniques.The simulation results show that no matter whether the jamming source is located in the range of antenna beam coverage of the seeker or not,both incoherent and coherent jamming can jam frequency-stepping millimeter-wave guided seekers.The energy of incoherent jamming is more dispersed,and the energy of coherent jamming is more concentrated.Therefore,a compound jamming strategy of inverse gain and active jamming is proposed in this paper,which can realize jamming of frequency-stepping millimeter-wave guided seeker and simultaneously realize self-protection of the jamming source.
