Transmission method of compressed data of radar clutter background image based on udp communication

Abstract

The invention discloses a method for transmitting compressed data of radar clutter background image based on UDP communication. The clutter background image is formed beam by beam according to the detection angle and detection distance to form the real-time memory data stream of the clutter background image, and the real-time memory The data flow forms a three-dimensional matrix; the sparse matrix of the clutter background image is constructed after optimization by the feed-forward neural network; the sparse matrix of the clutter background image is compressed to form a sparse matrix of the clutter background image to compress the data, and the data is passed through the radar in the UDP communication mode The radar data transmission subsystem in the detection system sends it to the radar display and control terminal system; and classifies the monitored display and control commands and the sparse matrix compressed data of the clutter background image into different priority queues; sends the control command data according to the priority Provide the radar detection system, and display the corresponding clutter background image through the display subsystem of the display and control terminal. The invention guarantees the reliability and real-time performance of data transmission and display, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of radar data transmission, in particular to a method for transmitting compressed data of radar clutter background images based on UDP communication. Background technique [0002] The radar detection clutter background image is a panoramic real-time detection of the detection site environment, so as to improve the accuracy of radar signal detection. Since the clutter background map data has the characteristics of high real-time performance, large data volume, high bandwidth occupation, and high system computing resources, and requires no packet loss in network transmission, how to quickly and effectively realize the clutter background map data Transmission is very important. [0003] At present, most of the clutter background images on the market are transmitted through TCP communication, non-real-time network transmission of clutter background image data or storage of clutter background images as pictures ...

Problems solved by technology

[0003] At present, most of the clutter background images on the market are transmitted through TCP communication, non-real-time network transmission of clutter background image data or storage of clutter background images as pictures to reduce the amount of data. However, this method has no effect on clutter The optimized processing of the background image data results in a large amount of data, and reduces the real-time performance of the clutter background image. Moreover, the use of TCP communication will increase the resource consumption of the network’s regular links, and increase the time when the display and control data is transmitted in the clutter background image.
