A Radar Accuracy Analysis System of Based on ADS-B and WEB

方位角、俯仰角、距离三维精度是三坐标雷达的重要技术指标,通常使用动态标校的方式进行标定;为解决动态标校试验周期长、成本高、难度大、在使用维护阶段难以实施等问题,文章介绍了一种基于广播式自动相关监视系统(ADS-B)的雷达精度准实时分析系统;文章从ADS-B数据率、位置精度、最大可接收距离等多个方面探讨了民航航迹用于雷达动态精度分析的可行性;采用Django框架设计、实现了WEB架构的雷达精度准实时分析系统;并使用高精度雷达对系统进行了验证、标定、系统误差补偿;最后,系统在某中远程雷达上进行多个批次测试,结果表明该方法有效且可行。

The three-dimensional accuracy of azimuth,elevation,and range is an important technical indicator for three-dimensional radars,which is usually calibrated using dynamic calibration method,but there are the problems of long dynamic calibration period,much cost,high difficulty,and difficulty to implement during the maintenance.To solve these issues,a near real-time analysis system of radar accuracy based on automatic dependent surveillance-broadcast(ADS-B)is introduced.The feasibility of using civil aviation flight path for radar dynamic accuracy analysis is discussed from the aspects of ADS-B data rate,aircraft position accuracy,and maximum receiver range.The Django architecture is adopted to achieve near real-time analysis system of radar accuracy based on the WEB structure,and the system is validated,calibrated,and conducted to compensate the system errs.Finally,the system is tested through a certain medium and long range radar.Experimental results demonstrate that the method is effective and feasible.
