Pulse System Fuze Target Simulator Overall Technical Research

The fuze target simulator was mainly used to provide the target echoes signal in the need of practice fuze under the almost real campaign condition. It would accomplish some properties test such as fuze start-up characteristic, coordination of fuze and warhead, anti-jamming and so on. The principle analysis and system designs of the fuze target simulator were mainly debated in this paper, and the generally of the blue-print was discussed too.This paper first took the single frequency carrier impulse system fuse simulator as background, the basic constitutes of the target simulator was introduced, and the integral design blue-print of the target simulator was studied too, including the design of the utter-and-receive system, criterion select and argumentation, the gain distribution, etc. It paid equal attention to the Broad Band frequency tracing methods, and the correspond procedure was designed. Then, the compose and main functional modules of the signal processing system were designed and analyzed in this paper, and the design project of the receiver and transmitter of the simulator were presented according to the criterion request of the impulse system, including the signal processing system, the video frequency echo simulation method of the practical test data was discussed too. Finally, the general problem of the single frequency carrier impulse system was discussed according to the fuze simulator, and the distill technique of the modulation period of the frequency modulation signal was discussed based on the time-frequency analysis methods.
