摘　　要：针对伪码脉冲体制的引信,采用近场分布计算方法分析了近距离目标回波功率变化,结合由于收发开关失配造成的功率损失,得到了引信接收机灵敏度特性理论结果。并用射频仿真方法模拟近距离目标,其中采用光纤延迟线将引信信号延时一个编码周期实现零距离延迟,验证引信真实灵敏度特性,最后给出了结论。The echo signal power＇s variation of a near-zone target was analyzed by near-field distributing algorithm for the pseudo-noise pulsed fuze system.Considering the power loss caused by the mismatch of transmit-receive switch,the theoretical results of fuze-receiver＇s sensitivity characteristic were obtained.A near-distance target was simulated by RF simulation technology,in which the fuze＇s emission signal is delayed with fiber-delay-line for whole coding period.This simulated target was used to verify the sensitivity characteristic of a real fuze-receiver and the conclusion was presented.
