The Method of Solving Signal Delay Based on Electric Probe Scanning Principle

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.
