摘要
综合考虑飞机实际飞行中存在多个航路转弯点及空中交通管制辅助系统需满足实时准确性的要求,设计了一种改进型的中期冲突探测算法。以雷达获取的飞机的当前位置和速度矢量作为初始状态,再结合航路飞行意图信息和转弯后的航迹误差积累方法,计算整合后的各航路分段冲突发生的概率来预测冲突发生的可能性。仿真实验结果表明,该算法能有效地用于中期冲突探测。
To solve the problem of multiple turn waypoints in the actual flight and the requirement of accuracy and real-time in air traffic control assist system,an improved conflict detection algorithm is designed.Using current position and velocity vector of the aircraft obtained by radar as the initial state,combined with the flight intent information of the route and the track error accumulation method after turn,it calculates conflict probability of integrated multi-route sections to predict the likelihood of conflict.Through the simulation and analysis,it shows that the algorithm can be effectively applied to mid-term conflict detection.
