Design And Implementation Of Simulation Platform For Satellite Borne Radar Monitoring System

This topic is about the simulation of the satellite borne radar system.Spaceborne radar is a hot topic in the field of radar research in recent years.On the one hand,it overcomes many shortcomings of the ground radar and the carrier radar,and has the ability of all-weather,all day long time,the ability of the early warning of the strategy,the tactics and the battlefield.On the other hand,it is not easy to be local or reconnaissance radar,concealment and fight ability,it is suitable for the monitoring and defense of ballistic missile.At first,this paper introduces the background,significance and research status of the subject,and analyzes the necessity of the research on the satellite borne radar and the research status of the domestic and foreign countries.Then the geometric model of the spaceborne radar is studied,including the geometric model of the radar beam and the geometric model of the target trajectory,and the problem of the coordinate system and the coordinate transformation are discussed.Next,based on the principle of radar,the third chapter introduced two waveform of radar,radar operating environment common clutter(Miscellaneous wave model and the classic clutter modeling method),the composition of the radar echo signal and ray method has been given emission signal,clutter,noise signal,radar echo signal of MATLAB modeling method.Finally,based on the basic principles of radar signal processing,the paper focuses on 4 processes,such as pulse compression,threshold detection,moving target display and moving target detection,MTI and MTD is one of the key content of this topic,the last two sections of this chapter are discussed in detail the two techniques,emphatically introduces the principle of both,and compare their advantages and disadvantages and gives the results of MATLAB simulation comparison.In the next chapter,the GUI interface of the satellite borne radar monitoring platform is designed,and the integrated simulation process is integrated into a user friendly interface.The last chapter summarizes the research results of this project,and puts forward some problems which need to be considered.
