A Radar Accuracy Analysis System of Based on ADS-B and WEB
The three-dimensional accuracy of azimuth,elevation,and range is an important technical indicator for three-dimen-sional radars,which is usually calibrated using dynamic calibration method,but there are the problems of long dynamic calibration pe-riod,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 a-viation 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.
