摘要
抗干扰性能是雷达的重要战技指标,干扰环境的逼真度直接影响雷达的作战效能评估。通过分析现代雷达系统抗干扰性能测试需求,采用数字射频存储方法构建了雷达抗干扰测试系统,并对系统的功能和原理进行设计和介绍;同时,通过对目标及回波、欺骗干扰、背景杂波以及压制性干扰进行数学建模,并依托数字射频存储系统,给出了各种干扰信号仿真实现方法。经过仿真测试应用,本文给出的宽带雷达抗干扰仿真测试系统设计方案,能够产生满足各类雷达装备测试需求干扰信号环境,为检验复杂电磁环境下雷达抗干扰性能提供了支撑。
Anti jamming performance is an important technical index of the radar,and the fidelity of the jamming environment directly affects the operational efficiency evaluation of radar.According to the demand of modern radar anti-jamming test,a simulation test system of radar anti-jamming based on DRFM is designed,and the system function is described.At the same time,target echo,deception jamming,passive clutter and masking jamming mathematical models are constructed;each kind of jamming signal realization method based on DRFM is given.The results of simulation and test show that the radar anti-jamming simulation test system design scheme presented in this paper can meet the needs of all kinds of required jamming signals and the requirement for testing various radar systems,which provides method for the inspection of radar anti-jamming performance under the complex environment.
