Data Fusion of ADS-SSR in Air Traffic Management

Xue Zhang, Zhang Qishan

Open publisher page 0 citations

Abstract

The application of Secondary Surveillance Radar (SSR) and Automatic Dependent Surveillance (ADS) have been applied in Air Traffic Management (ATM) system widely, especially in terminal domain. The characteristic and limitation of SSR and ADS in civil aviation are analyzed. The different affections of basic ADS contracts and extended ADScontracts to tracking precision are also deeply studied. A model and algorithm of the data fusion of ADS SSR in civil aviation are presented for improving the tracking precision. The numerical simula tion shows that this model and algorithm are effective. It is helpful for ATM system to have a continuous and reliable surveillance in a whole flight.
