摘　　要：针对无人靶机体积小,结构尺寸限制多,采用无源方式难以实现低频段RCS逼真模拟的问题。设计了一种低频段RCS有源模拟方式,在无人靶机有限空间下可实现低频段RCS模拟,同时又不影响无人靶机高频段RCS特性。通过暗室试验验证,验证了设计方案的可行性。The problem of low frequency RCS lifelike simulation is difficult to be realized by passive method because the size of unmanned target drone is small and the structure size is limited. A low frequency RCS active simulation method is designed,which can realize the low frequency RCS simulation in the limited space of unmanned target drone without affecting the characteristics of the high frequency RCS of unmanned target drone. The feasibility of the design scheme is verified by chamber experiment.
