Research on detecting sensitivity of capacitance proximity fuze

为提高电容近炸引信的探测距离,从物理概念和信息传输角度建立了电容引信探测灵敏度模型,得到了探测灵敏度的微分表达式;从探测电路灵敏度和信号处理电路灵敏度分别分析了影响探测灵敏度的参数及其影响关系,最后给出提高电容近炸引信探测灵敏度的行之有效的途径。

In order to improve the capacitance fuze detecting distance, the detecting sensitivity model is formed separately from physical concept and signal transmission. The differential coefficient expression of detecting sensitivity is deduced. Then the parameters which influence the detecting sensitivity are researched from detecting circuit and signal processing circuit. In the last, the effective means are put forward to improve the capacitance fuze detecting sensitivity.
