基于ADS⁃B技术的地空导弹雷达校飞系统设计

Design of ground⁃to⁃air missile radar flight calibration system based on ADS⁃B technology

地空导弹雷达装备在维修之后需要进行校飞才能确定探测精度是否符合要求。传统的方法是协调空军飞机进行校验飞行。为了解决地空导弹雷达校飞需要协调军用飞机,且耗费时间长、校飞成本高,故设计了一种自动捕获民航飞机飞行数据和雷达探测数据的校飞系统。首先使用数字调谐器和解调器构建数字无线电接收模块;然后采用数字无线电方式接收民航飞机广播的ADS⁃B数据,按照雷达数据要求解析出飞机坐标;采用摄像头自动捕获雷达探测数据;将从ADS⁃B数据中解析出来的飞机坐标和地空导弹雷达对该目标的探测数据进行比对,输出校飞结果记录,从而实现地空导弹雷达校飞。应用结果表明,该系统使用方便,校飞成本低,为地空导弹雷达校飞工作提供了一种有效的手段。

The ground⁃to⁃air missile radar equipment needs to be calibrated after maintenance to ensure that the detection accuracy meets the requirements.The traditional method is to coordinate the air force aircraft for flight calibration.In order to solve the problems of long time⁃consumption and high cost caused by coordinating military aircraft into flight calibration of ground⁃to⁃air missile radar,a flight calibration system is designed to automatically capture the flight data of civil aircraft and radar detection data.The digital radio receiving module is structured by digital tuner and demodulator.And then,the ADS⁃B data broadcasted by civil aviation aircraft is received in the manner of digital radio,and the aircraft coordinates are parsed according to the requirements of radar data.The radar detection data is captured automatically by camera.The aircraft coordinates parsed from ADS⁃B data are contrasted with the target detection data from the ground⁃to⁃air missile radar,and the record of flight calibration result is output,so as to realize the flight calibration of ground⁃to⁃air missile radar.The application results show that the system is easy to operate and has low cost of flight calibration,which provides an effective means for flight calibration of ground⁃to⁃air missile radar.
