Abstract : The patent application relates generally to seafloor mapping systems and more particularly to such systems generating a stereo-film of the seafloor topography. The sea floor mapping system uses echo signals from a pair of towed, side-looking sonar transducers to generate in real time a roll of photographic film which after conventional processing can be directly viewed in a stereoscope to produce a three-dimensional illusion of seafloor topography.
