摘要
针对飞机在航路飞行时航迹变化的一般情形,考虑预估航迹可能存在的各种误差,修正了航迹改变后的航迹预估误差协方差矩阵,用于改进了的三维飞行冲突概率计算方法。最后用Monte-Carlo方法验证了计算结果的正确性并对结果进行了分析。
Considering the general case of the trajectory position alteration.This paper considers various probable error of course prediction and corrects the error convariance matrix of course prediction after altering the trajectory position.And then the above method is used for three dimensional improved flight conflict probability algorithm.According to the uncertainty of actual trajectory position base on the above method,the conflict probability is estimated on the whole airway in statistics.At last,the paper presents a Monte-Carlo validation of the algorithms.
