The Study On Modeling And Simulation Of Monopulse Radar Seeker

In order to evaluate the efficiency of exact homing weapon system, it is necessary to model and simulate it by use of computer simulation. It can find out the battle sky of weapon system efficiently, and improve the cost-efficiency ratio on the development of missile weapon system. So it is an important means to develop the modern missile weapon system. This dissertation is focused on the study of modeling and simulation of active monopulse radar seeker.In this dissertation, the theory of active monopulse radar seeker is firstly given. And signal model sent and received of radar seeker, signal processing model, range tracking model, angle tracking model, proportional guiding model and so on are established by coherent video signal simulation. Simulation is carried out and the results verify the efficiency of these models. Based on these models, considering the "trigonal state" needed when the decoy is released, decoy echo model is established; and the interferential effectiveness of the decoy on seeker's angle tracking is analyzed. Finally, eliminated by miss distance of interception missile, the interferential effectiveness of decoy's parameters set is further discussed by system simulation, and the result is propitious to select logical decoy's parameters.
