A “swath-sounding” sonar system is one that is used to measure the depth in a line extending outwards from the sonar transducer. Systems acquire data in a swath at right angles to the direction of motion of the transducer head. As the head moves forward, these profiles sweep out a ribbon-shaped surface of depth measurement, known as a swath. Current swath sounding systems utilize two different technologies to achieve bathymetry measurements across a “swath” of the sea floor: 1) Beam forming (multibeam echo sounders), and 2) interferometric or phase discrimination sonars. Both of these techniques have their merits, however the same end results are achieved
