Source localization in shallow water is a crucial issue in underwater acoustics. The aim of this work is to propose efficient methods to perform source localization in depth and range using a single hydrophone. As a filtering method matched to single hydrophone configuration has been developed, the normal mode propagation model is considered. Several methods are exposed: incoherent matched mode processing (MMP), coherent MMP, a source depth estimation proposed by Nicolas et al. and a range estimation that we have developed. Methods are applied and compared on a real dataset.
