Localização de cetáceos a partir de assobios emitidos com análise da interferência de vida ao efeito Lloyd-mirror

Abstract

This master's thesis presents a technique for estimating the position via a sound source of a whistle broadcaster. The methodology consists of correlating the interferences generated by the Lloyd-mirror e ect between the whistling feedback (detected by the hydrophone) and the whistles generated by the various depth and distance scenarios allowing to obtain the scenario that most closely approximates the whistling feedback. For this, this study was elaborated from recordings of guiana dolphin whistles (Sotalia guianensis) and bottlenose dolphin (Tursiops truncatus). The tests demonstrated the ability of the algorithm to reproduce the observed whistles and the in uence of the depth of the receiver and the source on the quality of the results. Furthermore, the analysis of the result demonstrated the reliability of the algorithm.
