近炸引信信息通道的保护与泄漏

从引信为获取实施炸点控制的目标信息设置的信道，同时也是干扰机对引信进行干扰的干扰通道这个基本事实出发，提出了信道对抗和信道保护的概念，并揭示了引信中信道泄漏的存在以及干扰机利用信道泄漏进行干扰的威胁，具体的分析研究了自差式多普勒无线电引信的信道泄漏，分析了由于存在信道泄漏给引信干扰对抗双方所提出的新课题。

Information Channel Protection and Leak a Proximity Fuze

A fuze sets up a detection channel to control the burst point and this channel is also the jamming channel fo a fuze jammer. Based on this, we put forward the concept of information channel countermeasure, and channel protection. We also reveal that there exists channel leak in fuzes and the jammers can use the leak to jam fuzes. This paper also analyzes the channel leak of Doppler autodyne fuze concretely according to the theory of nonlinear oscillation. In the end, we analyze the new questions for both sides of studying fuze electronic countermeasures, which are caused by the existence of channel leak.
