Electromagnetic interference technique of transmitter and receiver modules for pulsed laser fuze

For the serious electromagnetic interference (EMI) problem in fuze arisen from volume constraints in the application of pulsed laser fuze to medium/small caliber conventional ammunition, the paper analyzes the necessity of adopting anti-interference measures internally with the principle of transmitter and receiver modules. Dual shielding which inhibits radiated interference (RI) and multi-filtering technique composed of linear impedance stabilization circuit, buffer network, CM-DM integrated choke, which inhibits conducted interference are proposed by analyzing EMI mechanism of transmitter module and receiver module. Simulations show that steel shield with the thickness of 1.55×10-3 m has good shielding effect on RI. Experiments prove that the peak value of receiver module interference s
