一种基于ADS-B信息的冲突告警算法

为了解决飞行流量持续快速增长导致的飞行安全问题，给出一种基于ADS-B信息的冲突告警算法。该算法的目的在于发现终端区或机场附近可能存在的飞行冲突，为飞行员采取避让措施提供足够的时间。算法主要由2个模型构成：第1个模型是飞行冲突区域划分模型，该模型包含保护空域(PAZ)和冲突空域(CAZ)2个区域；第2个模型是飞行冲突探测模型，该模型首先对冲突目标初选，然后对有可能发生飞行冲突的飞机从竖直和水平2个方向进行冲突探测并根据探测结果发出相应的告警信息。经大量的Monte-Carlo仿真实验表明该算法性能良好，能及时有效地发现飞行冲突，对确保终端区或者机场附近的安全有着重要意义。

A Conflict Alert Algorithm Based on ADS-B Information

Abstract: To solve the problem of flight safety that the sustained and rapid growth of air traffic flow leads to, the paper gives a conflict alert algorithm based on ADS B information. The purpose of the algorithm is to find the flight collision which may occur in terminal area or near the airport, and then to provide sufficient time for pilots to take avoiding action. The algorithm is mainly constituted by two models. The first model is flying conflict zoning model which contains the two regions of protected airspace (PAZ) and conflict airspace (CAZ). The second model is the flight conflict detection model which firstly primaries the conflict goal, then detects the possible conflict from both vertical and horizontal directions and issues the appropriate warning information based on the detection result. The large number of Monte Carlo simulation results show that the algorithm is of good performance, the flight conflicts can be effectively found in time, which is of great significance to ensure the security of terminal area or near the airport.
