摘要

In the context of the panoramic passive narrow band sonar, the aim of anAutomatic Data Tracking system (ADT) is to provide a single track for each vessel present on the observed area. In this paper, an alternative architecture is proposed. In this new architecture, called 'centralized', the track state vector consists of a bearing angle and a family of frequency lines and the detection to track associations are performed by using simultaneously all the available correlations of the sonar detection measurements. Performances evaluation on simulated data show that the centralized architecture noticeably increases the probability of track detection and strongly decreases the tracks cuts for the vessels with multiple frequency lines. Trials carried out on real detections obtained on a towed array are in accordance with these results.
