Abstract :
Describes an experiment utilizing existing shipboard sonar system transducers to obtain along and across track ocean bottom profiles from single return echoes. A short, sparse two dimensional receiving array was formed with sections of both the athwartships hydrophones and alongships projectors, of the vessel´s wide swath SASS bathymetry system. A standard navy BQN-3 transducer, of the ship´s along track profiling system, served as the transmitter. The limited data from the short arrays of 5 elements each were applied to the Burg implementation of a high resolution algorithm and an FFT beamformer for every sample or snapshot. Processed snapshots resulting from a single ping were then combined to form the along and across track profiles
