电容近炸引信的物理场特性分析

An Analysis on the Physical Field Characteristics of Capacitance Fuzes

电容近炸引信是利用振荡器在探测电极周围建立一个静电场进行工作的。本文将电容近炸引信简化等效为静态电偶极子,求解出其周围空间中距离偶极子为r处的场强。为了和其它原理的近炸引信的物理场特性进行比较,求解出时变场中电偶极子麦克斯韦方程的解。通过分析确认:利用静电场工作的电容近炸引信较之利用辐射场工作的其它近炸引信具有良好的定距特性、炸高散布小并具有反隐身技术的性能。

Capacitance fuze builds up a static electric field around the detecting electrods through the action of an oscillator . It can simply be taken as equivalent to a static electric dipoles , and then deduce the field strength at a distance r around the electric dipoles . A solution of Maxwell' s field equations of the electric dipoles in a time-variable field is deduced , thus permitting a comparison between the characteristics of the capacitance fuze and those of other kinds of proximity fuzes . The conclutions arrived at are : Capacitance fuzes using the electrostatic fields possesses better fixed distence characteristics , smaller spread of the burst height and bettr anti - con -cealment property when compared with other proximity fuzes using radiation fields .
