针对基于时间流的传统仿真手段不够精细的问题,设计了一种基于SystemVue 的数字射频存储器(DRFM)干扰数字流仿真系统。首先,设计了DRFM 干扰系统的结构,利用SystemVue 软件实现雷达和干扰部分的模块搭建;接着对DRFM假目标、射频噪声和间歇采样干扰三种干扰样式进行仿真实验,对比分析了不同干扰参数下的处理结果,并对间歇采样干扰的假目标幅度比进行仿真误差分析。仿真展示了整个干扰系统的可行性,对于装备实验和评估具有参考意义,也证明了SystemVue 仿真系统的模块化、数字化的优点和强大的射频仿真能力。

Aiming at the problem that the traditional simulation methods based on time flow are not precise enough, a DRFM jamming digital flow simulation system based on SystemVue is designed. First, the structure of the DRFM jamming system is designed, and the module building of the radar and jamming parts is realized by using SystemVue software. Then, simulation experiments are carried out on three jamming styles of DRFM false target, radio frequency noise and interrupted-sampling jamming. The processing results under different jamming parameters are compared and analyzed, and the simulation error analysis of the false target amplitude ratio of interrupted-sampling jamming is performed. The simulation demonstrates the feasibility of the entire jamming system, which is of reference significance for equipment experiment and evaluation, and also proves the modularity and digital advantages of the SystemVue simulation system and its powerful radio frequency simulation capabilities.
