Research on Track Correlation Algorithm of AIS and Passive Sonar Based on Fuzzy Mathematics

摘要:

针对 AIS 系统和被动声呐航迹的关联问题，提出了基于模糊数学的关联算法。该算法引入了 AIS 航迹可靠性的概念，提出了包含船舶与被动声呐间角度、距离、航迹可靠性等3个因素的关联隶属度函数与权重分配。通过实验验证，该算法可以较好地实现 AIS 与被动声呐间的航迹关联，为声呐信号复盘分析和自动化处理提供了借鉴。

Abstract:

Aiming at the correlation problem between AIS system and passive sonar track，this paper proposes a correlation algorithm based on fuzzy mathematics. This algorithm introduces the concept of AIS track reliability， and proposes the membership function and weight distribution that affect the correlation of three factors，including the angle，distance and track reliability between the ship and the passive sonar. Through experimental verification， the algorithm can better realize the track correlation between AIS and passive sonar，which provides a reference for the review analysis and automatic processing of passive sonar signals.
