Abstract

The invention discloses a secondary radar information processing system based on CPU (Central Processing Unit) and GPU (Graphic Processing Unit). The information processing system comprises system hardware including a radio frequency signal acquisition module, a computer, a GPU computing card and a communication network and system software including an operation system, a communication middleware,radar signal processing software, radar data processing software and management software. The total flow of information processing comprises the steps of sampling a radar signal; processing a secondary radar signal; processing secondary radar data; inputting, outputting, processing and controlling all the processes. By adopting the system, hardware bases of the radar system are general, the functions and the performance are defined by the software, and the defects of traditional radar in extensibility, diversity and reliability are overcome; meanwhile, the advantages of flexibility in use, higher reliability, lower use cost, lower energy consumption, updatability, extensibility and the like are brought, and the use efficiency of the system is improved.

Description

technical field [0001] The invention relates to a secondary radar information processing system based on CPU and GPU architecture. Background technique [0002] From the background of the application requirements of the radar system, there are three characteristics: [0003] First, the detection environment is gradually becoming more and more complicated, the radio spectrum resources are tight, and the complex electromagnetic environment requires the radar system to have the ability to improve the target detection performance through learning and adaptive processing according to the actual background; [0004] Second, the detection modes are gradually becoming diversified, such as meteorological detection, traditional aircraft monitoring and detection, UAV monitoring and detection, etc. Various detection objects and mission requirements require the radar system to be able to flexibly configure resources, expand functions and work modes; [0005] Third, multiple functions ar...

AI Technical Summary

Problems solved by technology

[0010] a) Poor scalability: with hardware technology as the core, the software is customized with the hardware, and the software and hardware are tightly coupled. After the system is developed, the functions and performance are solidified, the scalability is not good, and the use is not flexible;

[0011] b) Complex system and low reliability: At present, the core functional components of radar equipment are realized by dedicated chips and hardware circuits, with a large amount of equipment and low inherent reliability of the system;

[0012] C) Wide variety and high cost: radars are responsible for a variety of tasks, such as weather radars, air traffic control radars, surveillance radars, secondary radars, etc. There are many types of radars, functional components are not universal, and it is difficult to develop, produce, use and maintain equipment high, extremely costly
