Underwater Acoustic Localization

A 2-dimensional illustration of the three-ray model. When the surface and bottom are approximately flat in the operational area, this model enables non line-of-sight (LOS) based localization in the potential absence of the LOS signal component, e.g., due to an occluder.

This package contains a MATLAB code implementation of the localization method and the computation of the performance bound presented in [1].
