Because of the recent advances of the SAS research in the world, the coherency of sea bottom reverberation seems to become the key factor to realize the practical SAS motion compensation. By utilizing the principle of DPC, both the time and spatial coherency of bottom reverberation has been experimentally confirmed. This result significantly strengthens the robustness of the SAS motion compensation, because the existence of a prominent point-target in view will not be required.
