Design And Implementation Of A Two-dimensional Phased Array Low-slow And Small Radar Data Processing System

In recent years,the number of accidents caused by low slow small aircraft has increased,posing a major threat to the security of the country and society.Thus,how to implement effective supervision of this kind of aircraft has become imminent.Traditional radar has a poor detection effect on low slow small targets,so it is of great significance to design a low slow small radar with all-weather,high-precision tracking.At present,some low slow small radars use Track-While-Scan technology(TrackWhile-Scan,TWS),which have low tracking data rate,poor real-time performance,leading it easy to lose maneuvering targets.According to the beam agility characteristics of the phased array antenna,the radar in this work adopts Track-And-Scan technology(Track-AndScan,TAS),which can better solve the above problems,improve the tracking data rate of the radar,and increase the stability of tracking maneuvering targets.The paper mainly designs a two-dimensional phased array low slow small radar data processing system based on TAS technology,and realizes the application and adjustment of the system in real situation.First of all,the thesis introduces the development status of low slow small radars at home and abroad,as well as the research background and significance of TAS technology.Secondly,the basic theories of radar data processing have been studied in this thesis.The thesis introduces the target point processing steps and common algorithms for track-filtering,and describes the entire process from the beginning to the end of the track.Thirdly,the thesis describes the system composition of the two-dimensional phased array low slow small radar,which mainly explains the design scheme of the data processing system.Fourthly,the thesis describes the design and implementation of the network communication module,search data processing module,tracking data processing module,parameter and track information storage module in the data processing system.Finally,the correctness of each module in data processing system is verified by test.The results show that the two-dimensional phased array low slow small radar data processing system is able to search and track multiple targets in real time.
