摘　　要：研究对空榴弹的静电引信探测器采用电极扫描式被动静电探测体制.利用对空榴弹的自身高速旋转特性提高引信探测器的工作频率,缩短探测器滤波电路对目标感应信号的延迟时间,进而克服短路轴向探测电极式被动静电引信的信号延迟时间;理论分析及仿真实验结果表明,该方法可使电极扫描式被动静电引信滤波器对信号的延迟时间降至ms量级,满足对空榴弹引信探测器信号处理速度及起爆控制的实时性要求.An electric probe scanning type passive electrostatic detection system is proposed for use in antiaircraft shrapnel equipped with electrostatic fuze. High-speed rotation of the shell is utilized to increase the work frequency of the fuze detector, and to reduce the delay time of detector inducing signal due to filter circuit, and the general problem of long delay time of short circuit longitudinal electrostatic fuze is solved. Analysis and simulation test results indicated that the signal delay time is reduced to milliseconds by using the principle of electric probe scanning. It can meet the real time demands of signal processing and the detonation control in antiaircraft shell fuze detection systems.
