Abstract

The invention belongs to the field of air traffic control surveillance and especially relates to an ADS-B-based S-mode secondary radar information fusion system and a fusion method thereof. The systemcomprises a signal processing module, a track processing module and a fusion processing module. The input end of the signal processing module receives a first answering signal from a radar and a second answering signal from an ADS-B receiver integrated on the radar; the output end of the signal processing module is connected with the input end of the track processing module; the output end of thetrack processing module is connected with the input end of the fusion processing module; and the fusion processing module is used for carrying out track fusion to form a target track. The system, through full utilization of accuracy of ADS-B data information, makes a supplement for data information of a radar coverage area, greatly improves availability and tracking accuracy of a monitoring system, enlarges monitoring range, helps interval scheduling and facilitates a plane to realize uninterrupted and reliable monitoring in the whole light process.

Description

technical field [0001] The invention belongs to the field of air traffic control monitoring, in particular to an ADS-B-based S-mode secondary radar information fusion system and a fusion method thereof. Background technique [0002] With the leapfrog growth of the global economy and the rapid development of civil aviation, the air traffic will become more and more busy in the future, which is very important to obtain accurate and reliable aircraft surveillance information, and at the same time requires the accuracy and safety of the air traffic control surveillance system. Higher and higher. The S-mode secondary radar provides more comprehensive surveillance capabilities and ground-air data communication capabilities for the air traffic control automation system, which can improve the surveillance capabilities of the secondary radar. The number of codes of conventional secondary radar is only 4096, and it is easily affected by crosstalk and confusion. However, S-mode second...
