Single Sensor and Compact Array Localization Methods

Abstract

This project developed automated methods to localize marine mammal using single hydrophone systems and compact arrays. Several algorithms were developed: A1 uses received level in addition to timing information to estimate range and depth from single sensor data in shallow water; A2 modifies a model-based multiple animal localization method for use on single hydrophone data in deep water; A3 separates impulsive sources based solely on inter-click (inter-impulse) intervals; and A4 extends model-based localization methods from widely-spaced arrays to compact arrays. When possible, localization results were used to study marine mammal behavior and bioacoustics.
