Design And Implementation Of One-dimensional Phased Array Radar Data Processing Module Based On Host Compute

The one-dimensional phased array radar(ODPAR)has short scanning period and flexible beam pointing.It can realize the working mode of searching and tracking at the same time.It is commonly used to detect low and slow targets such as unmanned aerial vehicles(UAV).However,with the development of UAV technology,the movement of UAV has become more and more flexible,which brings challenges to the accurate detection of one-dimensional phased array radar.This paper focuses on the data processing part of ODPAR,in order to design and implement the radar data processing module of the one-dimensional phased array radar.Firstly,this paper gives an introduction on the significance of the research aobut this topic,and summarizes the current native and foreign research status of radar data processing;Secondly,the theories of maneuvering target tracking and radar data processing are studied,including point-track preprocessing,track initiation,track filtering,track correlation and other processing algorithms;Thirdly,the overall scheme of ODPAR data processing module is designed based on the requirement analysis.The track filtering and correlation algorithm are simulated by MATLAB to select the suitable algorithm scheme.The track cannot be associated when the target stops and walks again,so the track correlation algorithm based on the stopping and walking model is designed to improve the ability of track correlation when target maneuvers;Then,the data processing module of the ODPAR is implemented based on the host computer,including three sub-modules: communication,data processing and display control.The multi-threaded framework is designed to combine each sub-module organically;Finally,the radar data processing module implemented in this subject is tested to verify whether the communication,data processing and display control functions meet the requirements.The experimental results indicate that the radar data processing module of ODPAR implemented in this topic meets various functional requirements.It can efficiently detect the target and maintain the correlation of target tracks when target maneuvers.This software has been put into use for more than half a year and basically meeting the needs of users.
