| dc.description.abstractEn | A new method for measuring the sound speed profile of the seafloor has been recently proposed (JASA, vol. 128, pp. 1685-1693): the image source method. This method is based on a physical model of the acoustic field generated by a point source and reflected by a layered media. Under the Born approximation, the reflected signal can be modeled as a sum of contributions coming from image sources relative to the seabed layers. Consequently, the seabed geometry and sound speed profile can be recovered by exploiting the localization of these images. We present here a study about the sensitivity with the relative noise level and the map mesh size in the localization of the image sources. | |
