Research On Radar Raster Display Technology

Rasier scan display has achieved more and more common applications in the field of present radar technology. As a kind of terminal display device, it is obtained much attention increasingly. Compared with the conventional random scan, raster scan has the advantages of high brightness, high resolution, clear image, steady display and no-glint, great display information capability, long stay and picture-controlled, etc.The paper introduces the basic principle and the total structure of the radar raster scan display and puts forward the practical project of the radar raster scan display. The studies of coordinate transform and video processing of radar raster scan display are placed emphasis on. Chapter 5 and Chapter 6 of the paper describe the circuit design processes of coordinate transform and video processing respectively, present the simulation results, complete design and simulation of the circuits under the environment of MAX+PLUS II and realize the relevant logic circuit design by using the programmable logic device CPLD of Altera.
