[Abstract]:Monopulse tracking radar can achieve high precision and high data rate continuous tracking measurement to single target. It is a kind of tracking and measuring radar widely used at present, which is mainly used in weapon control. It has good performance of ranging, angle and velocity measurement. With the improvement of radar function requirement, the research of new technology of radar system has been paid more and more attention. It is necessary to build a radar simulation system based on computer simulation technology, which is convenient for the study of high efficiency and low consumption. In this paper, the simulation system of monopulse tracking radar is built based on Matlab Simulink platform. Based on the time flow signal level, the radar system is simulated. The main work process of monopulse tracking radar is: according to the guidance information, the antenna beam is directed near the target, the small range search is carried out, and the target is detected. In the tracking state, the parameters of tracking are range, angle and speed. The four-dimensional continuous tracking and measurement of the target is realized through the ranging loop, servo system and speed measuring loop. In this paper, the task of the monopulse tracking radar system is first discussed. This paper introduces three main technologies in the radar system, including the measurement and tracking of the target angle, the measurement and tracking of the target range and the measurement and tracking of the target velocity. Then, according to the simulation requirements of monopulse tracking radar, the overall framework of monopulse tracking radar simulation system and the work flow of simulation system are put forward, and the building of simulation model and the development of simulation centralized control platform are introduced. Then, the modeling and analysis of each module in the simulation system includes environment model, transmitter model, antenna model, receiver model, signal processor model, measuring machine model, servo system model and system scheduling model. At last, the simulation system of monopulse tracking radar is built, and the range, angle and velocity tracking information are output. The simulation results are analyzed, and the correctness of the radar simulation system is verified.
