一种用于雷达性能测试的新系统已开始研制。该系统包括雷达目标模拟及有源电子干扰两部分,能在雷达工作频率范围内复制雷达信号的脉内调制特性,模拟常规雷达、捷变频雷达及各种特殊雷达的回波;能模拟目标的速度变化、距离变化及因距离变化而引起的电平起伏;模拟目标背景杂波及多路径效应,并能进行多目标模拟,在进行目标模拟的同时,还能模拟自卫式和支援式干扰,并有同时模拟噪声 A new system for radar performance testing has been developed. The system includes radar target simulation and active electronic jamming. It can replicate the pulse modulation characteristics of radar signals in the working frequency range of radar and simulate the echoes of conventional radars, frequency-agile radars and various special radars. The system can simulate the target Velocity variation, distance variation and level fluctuations caused by distance variation; simulate target background clutter and multipath effects, and can perform multi-target simulations, simulate self-defense and supportive interferences while carrying out target simulations Simultaneous analog noise
