Design Specifications for a Long-Range Swath-Mapping Sonar,
Abstract
Design specifications are presented for a transducer array operating at 3.5 kHz and capable of bathymetric mapping over a swath of at least 25 nautical miles across the ship's track. Beam shaping was determined solely by transducer placement. Specifications are given for the beam transmission patterns and comparisons are made to a hypothetical array which would illuminate the ocean bottom uniformly. Signal-flow and processing designs are provided for application of the array to the detection of large-scale bathymetric features above the mean ocean depth. The entire system will provide a coverage of 250 (n. miles) squared/ hour from a 10-knot research vessel. (Author)
