UDP communication-based radar clutter background image compressed data transmission method

Abstract

The invention discloses a UDP (User Datagram Protocol) communication-based radar clutter background image compressed data transmission method, which comprises the following steps of: forming a real-time memory data stream of a clutter background image from a clutter background image beam by beam according to a detection angle and a detection distance, and forming a three-dimensional matrix from the real-time memory data stream; constructing a sparse matrix of a clutter background image after optimization by utilizing a feedforward neural network; compressing the sparse matrix of the clutter background image to form clutter background image sparse matrix compressed data, and sending the clutter background image sparse matrix compressed data to a radar display control terminal system througha radar data transmission subsystem in the radar detection system in a UDP communication mode; classifying the monitored display control command and clutter background image sparse matrix compresseddata to form queues with different priorities; and sending control command data to a radar detection system according to a priority mode, and displaying a corresponding clutter background image through a display control terminal display subsystem. According to the invention, the reliability and real-time performance of data transmission display are ensured, and the method has a good application prospect.

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.
