Abstract :
Extension of the operational range of underwater location techniques has been related to the incorporation of reliable acoustic propagation models, that closely predict the behaviour of oceans. In this paper, the performance of ocean tomography and passive localization of underwater acoustic sources is studied, by analyzing the coupling of performance degradations imposed by modeling mismatches on the ability to estimate the position of acoustic sources
