Resumo: One of the currently exciting areas in SONAR research is in the use of acoustic channel models to improve SONAR systems. In this paper, we use the echo pattern at a single phone to localise a sound source in both range and depth in the ocean. To make the localisation robust, the signal processing is set-up with particular regard to which acoustic features are reliable and clear encoders of the source position. The resulting algorithm was tested using experimental data collected during INTIMATE’96- a shallow water experiment conducted on the Portuguese continental shelf[1]. The results show successful tracking over a period of several days encompassing two fixed 25-hour stations and an 18-hour period of ship manoeuvres.
