一种关于目标与安全管道相对位置估算方法

An Evaluating Method of Relative Position between Target and Safety Pipeline

针对靶场试验安全控制中目标与安全管道位置估算的实际需求,结合靶场实时数据处理要求,提出了利用滑动窗口技术,动态载入理论弹道数据,并采用折半查找和KNN查询相结合的思想实现了目标与理论弹道最近邻点查询,完成了飞行目标与理论规划航迹间的位置等参数偏差查询。利用区间估计原理,给出了目标与安全管道相对位置估算方法,解决了传统试验中无法对目标与管道边界的接近程度进行量化的问题。

Aiming to the actual demand of position evaluating between target and safety pipeline on safety control in range test, combining with the real-time data processing, it put forward that using of the sliding window technique, dynamica loading theoretical trajectory data and using technique of binary search and KNN query to realize KNN query between target and theoretical trajectory. Position deviation query between target and theoretical trajectory was finished. Evaluating method of relative position between target and safety pipeline was given based on the principle of interval estimation. The problem of close degree between target and safety pipeline that could not be quantitative analysis in the traditional interval test was resolved.
