| 摘 要： | 以静电平衡状态下导体具有的性质为理论依据,建立了两极板主动式静电引信的模型,并对其电场进行了分析,计算得到检测极板上电荷随弹目距离变化的目标特性曲线.设计了相应电路来测量检测极板上电荷的变化率,并介绍了后续信号处理电路的工作原理.得出结论:弹目接近过程中,检测极板上电荷的变化率逐渐增大,即电荷检测电路的输出电压逐渐增大;电路输出电压的分辨率与电极电荷量、极板及目标尺寸、极板间距以及弹目夹角有关,同时与弹目相对速度成正比.该工作对主动式静电引信的设计工作有重要的指导意义.

| Abstract: | Based on the properties of conductor in static equilibrium state,a model of active electrostatic fuze is built,then its electrostatic field is discussed,and the characteristic curve of the induced charge on test electrode vs.the distance between the fuze and target is obtained in this paper.A circuit is used to test the change rate of the induced charge,and the working principle of the signal processing circuit is proposed.The obtained conclusions are when the fuze gets close to the target,the change rate o... |
