The Study On Modeling And Simulation Of Anti-ship Radar Seeker

With the development of accurate homing technology and computer simulation technology, the modeling and simulation of the accurate homing weapon systems have been expanded from missile's control system's simulation to terminal guidance seeker system's simulation. This paper focuses on the study of modeling and simulation of the anti-ship radar seeker.The points of this thesis are mainly as follows:Firstly, the echo signal model of radar seeker is established by the means of coherent video signal simulation. Then according to the actual electrical machinery parameter, the corrective algorithm of terminal guidance radar seeker servo system is designed and the simulation model is established. Thirdly, the author study signal processing of radar seeker and establish the mathematical model of radar signal processing and data processing, and then the modeling of proportion guiding is established and a dynamic simulation result is provided. Lastly, appropriate evaluation indexes are established based on the missile impact. After that, the missile-ship engagement scenario is simulated under some conditions, and a few simulation results are then presented and discussed.The simulation system reflects the whole process of the missile attacked target comparatively truthfully, which is worthy of other radar seeker simulation using for reference and provides a good foundation for simulation and application of multimode seeker.
