摘　　要：瞬时测频接收机通常工作在复杂的电磁环境中,宽带的接收特性使其极易受到影响。针对瞬时测频接收机的工作机理,选取了连续波信号、高占空比信号、同时到达信号、低截获概率雷达信号等典型雷达信号样式,对瞬时测频接收机产生的影响,分析引起工作性能下降的原因和现象,并对部分结论进行了仿真实验验证,得到了与分析结论一致的实验结果。对雷达侦察装备研制和使用具有一定的借鉴意义。An instantaneous frequency measurement receiver often works in complex electromagnetic environment, It is very impressionable because of its wideband receiving characteristics. According to the working mechanism of the instantaneous frequency measurement receiver, some typical radar signal styles that could influence the instantaneous flequency measurement receiver, such as continuous wave signal, high duty-cycle signal, signals arriving at same time, low probability of intercept radar signal, were chosen. The reason and the phenomenon what causing the working performance dropped were analyzed, and several conclusions were approved by simulation experiments. The experimental results agree with the conclusions. It has certain reference significance for development and use of radar reconnaissance equipment.
