Design And Implementation Of Low-slow And Small Radar Data Processing And Display Control Software Based On C++

With the maturity of consumer-grade drone technology and the decline in production costs,the consumer market for small drones is extremely active,bringing convenience to people’s lives,but also threatening low-altitude safety deeply.Low-speed and small-target detection radar should come Born.Due to the rapid development of science and technology,the corresponding hardware equipment,algorithms and computer performance of low-slow and small radars are continuously optimized and improved,which makes the radar signal processing capability advance by leaps and bounds,and the output radar data volume and data rate are greatly increased,which requires corresponding radar data The processing system can handle a larger amount of data and continuously improve the efficiency of computing.Therefore,improving the real-time and accuracy of the radar data processing system becomes particularly important.The research in this paper is a PC software system based on pulse Doppler low-slow radar and display integration.First of all,this article introduces the research background and current status of low,slow and small target characteristics and radar data processing,and introduces related theories of radar data processing;secondly,according to the overall plan of the radar system,the radar host computer software is divided into four functions Modules,the realization schemes of four modules were respectively designed;again,the functional requirements of each module of the radar upper computer software system were realized according to the design scheme;finally,the function debugging of the radar upper computer software and the whole machine test in the field were carried out to verify the radar The processing effect of the upper computer software.The experimental results show that the radar host computer software in this paper can realize real-time detection and tracking of low and small targets,and can extract real target points from the target data with false alarm probability and form a stable moving track,indicating that the radar designed in this paper The host computer software has good real-time and accuracy,and meets the requirements of the system.
