摘要
分析目前雷达精度测量方法的弊端,介绍广播式自动相关监视技术(ADS-B)的基本原理和数据格式转换方法,并提出一种基于ADS-B数据的雷达跟踪精度计算方法。在利用ADS-B系统进行多目标跟踪的过程中,运用改进的数据关联算法(MPDA)和基于"当前"统计模型的自适应卡尔曼滤波算法,计算出雷达的跟踪精度。仿真结果表明:运用该方法 ADS-B系统能够高精度地跟踪目标,可以满足测量雷达跟踪精度的要求。
The current measurement methods for radar precision were analyzed and the principle and data format conversion of the automatic dependent surveillance-broadcast（ADS-B） were introduced.After that,a calculation method of radar tracking precision was proposed on the basis of ADS-B.In the process of multi-target tracking with ADS-B system,an improved probabilistic data association algorithm and the adaptive Kaman filter based on current statistical model were used and then the radar tracking precision was calculated.Computer simulation by MATLAB shows that the ADS-B system can track target in high accuracy and meet the requirements of measuring the radar tracking precision with this method.
