基于航迹预测的飞行冲突探测

基于飞行器飞行途中的随机影响及观测仪器的误差影响,给出了常速模型的冲突探测模型。重点讨论2架飞行器靠近飞行的情况,采用卡尔曼滤波理论,预测2架飞行器的相对航迹。然后依据相对航迹,计算2架飞行器在各时刻的距离。最后根据冲突条件判断冲突是否存在。该方法不仅从模型上保证了更接近飞行器的实际飞行情况,而且计算机仿真结果表明该方法能有效地进行冲突探测。

Flight Conflict Detection based on Flight Path Prediction

Based on the stochastic influence of flight vehicle and off-carriage instrument's error on the way,the paper proposes the conflict detection model of constant velocity model.The paper focuses on the situation of two flight vehicles flying close and proposes using Kalman filter theory to predict the relative track between the two flight vehicles.Then,according to the relative track,it calculates the distance between the two flight vehicles.Finally,according to the conditions of conflict,it estimates whether ...
