Commonly, motion compensation methods of shipborne HFSWR describe each aspect of the 6-DOF motion as the superposition of …
WebModern bathymetric mapping employs shipborne sonar sensors. While very effective at mapping the seafloor surface, it is impossible to acquire bathymetric data in the nearshore as the depths do not allow operation of a ship.
