Small distance is not present, and defining the distance is minimum range, if the distance is less than minimum range, minimum range is equal to the distance；
If alignment failure, next time point is to determine time point in circular in definition masters track, executes the judgement step
Suddenly, until choosing into masters track the last one time point；
Defining the corresponding location point of minimum range in two path segments is the nearest location point of the distance.
9. the Performance Evaluation platform of on-air collision detection airborne equipment according to claim 1, which is characterized in that
The check and evaluation report and monitoring and evaluation report include accuracy, false alarm rate, false dismissed rate, repeat alarm rate and late police
Rate.
