Design of fire control system of electrostatic fuze based on FPGA

Based on the application of FPGA, proposed a new design method of fire control system for electrostatic fuze aiming at the problem that design of fire control system of electrostatic fuze's circuits is quite complicated. This fire control system comprises the current detecting electrostatic detection circuit and the digital circuit composed of the modules of filter, differentiation and zero-crossing detection. This fire control system has the advantages of simple system structure and flexible design mode. Simulations indicate that this fire control system can enhance the electrostatic fuze's ability to identify the target's signal and thereby improve the fuze-warhead efficiency.
