A Research On The Combined Terminal Guidance Emulation System For Anti-galley Missile

This work designs and implements the combined terminal guidance emulation system for anti-galley missile with the research background of anti-galley missile warcraft jamming evaluation, and puts up a platform for warcraft jamming evaluation.The procedure of combined terminal guidance for anti-galley missile is emulated with the proportional guidance and the bimodulus combined datas in the whole system, and the datas are simulated with the reality datas of the ground unimodular terminal guidance sensor. To preserve the reality of the actual battlefield and reduce the expenditure of experimentation maximumly is the all and the one target of the system. The performance of the system reliability, which achieves design specification.The combined terminal guidance emulation system composition for anti-galley missile is analysed, the layout of the system is introuducted, the function of the shooting range signal acquisition subsystem and the combined terminal guidance emulation subsystem is analysed, and the bottleneck of the system is pointed out.The design options of the shooting range signal acquisition subsystem is put forward.The front end conditioning circuit, the front end isolation circuit, the long-range analog signal circuit, the back end isolation circuit, the multicenter signal acquisition circuit and the multicenter signal acquisition software are implemented. The debug procedure and debug method are introduced, the corresponding questions are settled, and the comprehend in design and debug the subsystem is summarized.The software flow of the combined terminal guidance emulation subsystem is put forward, and the functional modules of the subsystem are introducted. The dimensional transformation, the coordinate transformation from earth coordinates to polar coordinates, the compute for the absolute location of the observed object, the bimodulus combined compute for the location of combined object, and the proportional guidance are implemented.At last, This work provides the summarization of the work and the content of the future research.
