| 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。

| Abstract: | 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 se... |
