Abstract

Disclosed is a method for producing radar display images and a system thereof, wherein, the system comprises: two A/D converters for respectively implementing sampling processing to radar interface image video signals and radar original image video signals with VGA formats, and respectively outputting horizontal synchronizing signals, field synchronizing signals and digital RGB signals; a buffer for carrying out buffer processing to radar interface image video signals and radar original image video signals; and a radar image generation module realized through an FPGA chip for implementing synchronous processing to radar interface image video signals and radar original image video signals and looking up table indexes by colors for implementing synthetic processing so as to generate the radar display image video signals. The method and system need not use the special radar image generator, and can utilize the general control program to realize the superposition processing to radar original images and radar interface images in the FPGA chip, thereby producing the radar display images meeting the requirements of radar image display terminals.

Description

technical field [0001] The invention relates to radar image processing technology, in particular to a method and system for realizing the superposition processing of radar original image and radar interface image in FPGA chip to generate radar display image. Background technique [0002] At present, my country's active radar display images are mainly produced by graphics generators that generate radar interfaces, and then superimpose the original radar images. Although this method can generate images faster, it has many disadvantages: [0003] 1. The development is difficult and inflexible: because the graphics generator programmers are professional in programming, the development is not universal, the graphics production is complicated, and the development progress is slow. [0004] 2. Radar image production is greatly affected by devices: due to the use of special devices to generate radar images, the product life is short, and a product is often threatened by device obso...
