Contrast functions G for depth source localization by F-K approach combined with source spectrum estimation. The simulation is given for source ULF-2 located at 70 m of depth and 10 km distant from the HLA. (a) shows the gain given by taking into account the estimated spectrum of an unknown source for localization method without mode signs. (b) shows this gain in case of localization algorithm with integrated mode signs into the contrast function.
