Digital Universal Video Target Simulator Technology

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 different systems of fuze echo signals were introduced too. In the study of integral design blue-print of the target simulator, discuss how to design the compose and main functional modules of the signal processing system according to the criterion request of the simulation system and the video frequency echo simulation method of the Doppler and distance data was discussed too. Discuss one kind of digital multiplier based on FPGA. AS the general problem of the fuze simulator, discuss two kinds of distance simulation system, and realization based on FPGA. Study the distill technique of the modulation period of the frequency modulation signal was discussed based on the time-frequency analysis methods and zero-cross detection technology. Finally, discuss solid target and how to make the clutter model in computer.
