脉冲体制引信近距性能分析

Analysis of the Near Zone's Property of Pulse System Fuze

脉冲体制近炸引信为了提高收发隔离比,通常采用高频收发开关,虽然解决了引信收发共用天线问题,但会造成引信近距灵敏度下降。文章分析了造成引信近距探测性能下降的原因,提出了改进引信近距性能的具体方法。

In order to raise the isolation of transmit-receive, high frequency on-off switch is ofen used in pulse system radio fuze. The on-off switch solve the problem of transmit-receive shared antenna, but it will lead to the drop of the fuze＇ sensibility in near zone. In this paper, an analysis of how to reduce for sensibility of fuze in near zone is introduced, and also put forward the methods of improving the near zone＇s property of pulse system fuze.
