航空器轨迹冲突探测方法的改进与仿真

针对传统轨迹冲突探测方法忽略航空器外形轮廓会造成空域浪费的问题,对冲突探测几何近似法进行改进.考虑航空器外形尺寸对轨迹冲突探测结果的影响,提出扩展保护区的概念,给出相应几何近似法的计算步骤,并通过仿真实验对所提出的几何近似法的有效性进行验证.仿真实验表明:所提出的几何近似法的结果能反映轨迹冲突概率的变化趋势,更接近冲突概率的真实情况.

Improvement and Simulation of Aircraft Trajectory Conflict Detection Method

In order to solve the airspace waste problem caused by traditional trajectory conflict detection methods which usually ignore the aircraft contour, the geometric approximation method (GAM) for conflict detection is improved. Considering the effect of aircraft contour size on the trajectory conflict detection result, the concept of extended protection zone is proposed at first, and then the steps of corresponding GAM are given. The validity of the proposed GAM is verified through simulation experiments. The simulation experiments show that the result of the proposed GAM could efficaciously reflect the variation trend of conflict probability, and is closer to the true value of conflict probability.
