基于航迹质量评估的雷达和ADS-B数据融合方法
Data fusion method of radar and ADS-B based on track quality assessment
摘要
Abstract
The data fusion of radar and automatic dependent surveillance-broadcast(ADS-B)is the effective me-thod to surveille the'black flights'and flying birds.However,the tracking performance of the two sensors has large differences and is easy to be fluctuated,which will bring a decline in fusion accuracy.A data fusion method of radar and ADS-B based on track quality assessment is proposed.Firstly,the effects of local track accuracy,data update times and sensor measurement errors on local track quality on corresponding assessment factors are analyzed and quantified.And then,these assessment factors are combined to calculate the quality weighting factors of the local track,and the asynchronous track fusion processing of radar and ADS-B is completed based on the distributed fu-sion structure.Finally,the feasibility and effectiveness of the proposed method is verified with simulation experi-ment and application.The results show that the proposed fusion method can effectively improve the fusion accura-cy,and the tracking errors are better than the traditional algorithms when the sensor tracking performance fluc-tuates.关键词
