样本匹配算法在鱼雷弹道融合中的应用

The application on the ballistic trajectory fusion of torpedo based on exemplar matching algorithm

通过分析鱼雷对抗试验中获得的内外测弹道数据的特点,在比较多种曲线匹配算法的基础上,提出了一种基于样本的匹配算法。该方法利用弹道曲线上的点对应的矢量作为特征无关量信息,在合理选取样本点基础上,采用最大相似性准则对弹道曲线进行匹配,找到曲线最佳匹配段,从而对准内外测弹道的时间基准,以用于弹道融合。

This paper analyzes the characteristic of the data generated by torpedo＇s sail. Comparing some algorithms, an algorithm based on exemplar matching is proposed. This method uses the characteristic of the rationally selectd swatches on the ballistic trajectory as the matching object,and adopts the principle of maximum comparability to match the points on the both trajectories which have the same time. It is proved that this method is stable, efficient and applicable.
