Abstract: 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 .
