基于Kalman滤波的飞行冲突探测

Aircraft Conflict Detection Based on Kalman Filter

基于飞行途中的随机影响及观测仪器的随机误差的考虑,从随机框架的角度提出了Kalman滤波作为冲突探测的一种方法.该方法不仅从模型上保证了更接近飞机的实际飞行情况,而且理论和计算机模拟结果也都表明该方法不但能对明显存在冲突的态势给出准确的预报,对于那些由于随机因素而产生的潜在冲突也能给出一定概率的预报.

Consider the affection of situation and erros of apparatus, and introduce a confilct detection approach based on Kalman filter from the stochastic frame. This model is more close to the reality situation. The theroy and computational results show that this approach not only can give prediction when a visible confilct exists, also can give some certain prediction when a potential conflict exists by the random factors.
