引信雨场干扰机理的研究

On the Mechanism of Rain Field Interference in Proximity Fuzes

在雨场对无线电近炸引信和电容近炸引信干扰机理的研究中,介质影响可以忽略不计,干扰主要来自雨滴和引信碰撞时雨滴发生形变对引信的影响.通过研究和实验验证,得出了雨场对近炸引信干扰的三大要素是:雨滴直径D、碰撞位置S和相对速度v。

Describes the mechanism of rain field interference in radio proximity fuzes, including the capacitance fuzes. The interference comes mainly from raindrop deformation when a raindrop collides with the fuze, the medium ' s influence on the interference being neglected. Through analysis and experiments, 3 main factors of rain field interference on a proximity fuze have shown up, namely the diameter D of raindrop, the colliding position and the relative velosity between the raindrop and the fuze.
