Research on Combined Air Collision Prevention Technology

摘要

As number and frequency of flight is increasing, the safety of air traffic becomes important issue of concern. Currently what is used to ensure the safety of air traffic contains air traffic control (ATC), airborne collision avoidance system (TCAS) and automatic dependent surveillance technology (ADS-B), which has been widely used. But they are independent of each other, and data fusion is not sharing, which will result that the track data of flight is not the optimization and the judgment of whether there is a potential safety hazard exists is not accuracy. This article made three kinds of technology into combination, using kalman filtering method to get data and track on the three ways for fusion, which gave the best estimate of the aircraft track, and improved the accuracy of air traffic situational judgment.
