基于UPF的中程飞行冲突探测

Mid-range aircraft conflict detection based on the unscented particle filter

2000年,Prandini等建立了飞机位置的概率模型,该模型将飞行扰动的方差作为全程飞行时间与路程的函数,基于此模型,他们提出了中程飞行冲突探测的随机化算法.本文作者将飞行扰动作短时处理,建立了包含雷达观测误差在内的一个更精确、更符合实际的概率模型,并提出了基于UPF的中程飞行冲突探测算法.

The probabilistic model for predicting the aircraft position in the mid-term future was developed by Prandini et al. in 2000, in which the variance of the perturbations entering the aircraft motion was formulated as a function of total flight time and distance. A randomized algorithm for predicting mid-range aircraft con- flict detection was introduced by them. In this paper, the authors propose a more accurate and practical proba- bilistic model in which the perturbations are treated in a short and predetermined time, and the radar observation errors are included. Further, the mid-range aircraft conflict detection algorithm is proposed based upon the unscented particle filter.
