Design And Implementation Of A/R Display Of Coastal Defense Radar Simulation System

Coastal radar is an important part of our army coastal information technology investigation.At the same time,coastal radar basic training has great demand because of the combat duty of radar equipment and the technical support.However,there are many shortcomings use the coastal radar training and the research of radar simulation system started late in our country,even has not any corresponding examples.Therefore,in order to meet the needs of coastal radar training better,it is great necessary for the simulation of coast defense radar system.The paper concentrates on the study of coastal defense radar simulation system A/R.The stage of data preprocessing,the paper uses Mercator projection to change the coordinates of the target trajectory and using the method of piecewise linear compression of waveform data in real time to compress the data of the target.The stage of key technology research,put forward to use the improved mixed congruence method simulation clutter,at present there are no relevant reference examples,at the same time,combining the improved mixed congruence method and the A/R gain to make it more close to actual situation which gain control defense radar clutter wave.Put forward to number of scanning lines adaptive target wave superposition for simulation of R display.Solve a problem which R display only shows the current position of target echo lead to cannot accurately to judge the nature of the target.The weighted coefficient method to deal with the superposition of multiple echo.The stage of graphics drawing,using GDI+ double buffering and multithreading technology to simulate A/R display.Finally,the simulation results and some key codes are given.Simulation results show that achieved good simulation effect for coastal radar simulation system.The operator can judge the target and measuring distance by the display results.It not only can be applied to the coastal defense radar grassroots training better,but also can solving problem of shortage of grass-roots training support equipment effectively.
