Abstract: 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.
