Abstract

This paper describes a tracker specially designed to track clicking beaked whales using widely spaced bottom-mounted hydrophones, although it can be adapted to different species and sensors. The input to the tracker is a sequence of static localization solutions obtained using time difference of arrival information at widely spaced hydrophones. To effectively handle input localizations with high ambiguity, the tracker is based on multi-hypothesis tracker concepts, so it considers all potential association hypotheses and keeps a large number of potential tracks in memory. The method is demonstrated on actual data and shown to successfully track multiple beaked whales at depth.

摘要

本文描述了一种专门设计的追踪器，用于使用间隔较远的海底水听器追踪柯氏喙鲸，不过它也可适用于不同物种和传感器。该追踪器的输入是一系列通过间隔较远的水听器利用到达时间差信息获得的静态定位解决方案。为了有效处理具有高度模糊性的输入定位，该追踪器基于多假设追踪器概念，因此它会考虑所有潜在的关联假设，并在内存中保留大量潜在轨迹。该方法在实际数据上得到了验证，并显示能够成功追踪深处的多头柯氏喙鲸。
