声呐数据融合的期望最大化（EM）算法

Application of the EM algorithm for the sonar data fusion

摘要: 现代舰艇通常装备有多部声呐,对这些声呐的检测信息进行融合,并加以综合利用,以提高整个声呐系统对目标的定位精度具有重要的现实意义。本文利用EM(Expectation Maximization)算法,对多部声呐检测的方位信息进行了数据融合,获得了满意的结果。该算法也可应用于其他水下定位系统。

Abstract: Modern warship and submarine are generally equipped with several sonar. It is of great significance for improving positioning accuracy of the sonar system to integrate the bearing measurement information from these sonars by using data fusion. In this paper, BM algorithm is used to fuse the bearing information from these sonars. Results show that this algorithm can achieve a satisfactory accuracy.
