Development Of Radar Terminal Type-A Display System Based On ELD With Dual Scan

ELD with dual scan (ELD-DS) is a kind of novel electroluminescence display in raster scan that is different from CRT in that it is digitally drived and matrix-addressing. After analyzing previous CRT display systems, this paper proposed a kind of ELD-DS based display system solution and its image formation algorithm. In addition, this paper designs the hardware and software of this system. This paper designs the hardware system of the radar terminal type-A display system based on the ELD-DS. The hardware system consists of display drive interface, i386EX subsystem and radar video signal processing subsystem. In the radar video signal processing subsystem, the processing techniques of signal segmentation and maximum velocity of radar moving targets are proposed. Accompanied by the design of hardware system, in the design of software, this paper designs the embedded operation system, application routine and ISP software. The software runs this display system and, makes system upgrade and debug more convenient. Finally, this paper studies the application technique of ISP. The ISP based system debug technique is proposed in this paper.
