A New Concept for a Rapid Surveillance Acoustic Bathymetric System.
Abstract
An extensive study of existing data was made to determine the feasibility of using an airborne acoustic system for bathymetry of shallow waters. The total signal sound pressure for acoustic frequencies of < or = 2000Hz, is calculated as -132db for the case where the transceiver is located 10 meters above a smooth water surface and the water depth is 10 meters. Estimates have been made for additional losses due to rough surfaces and higher acoustic frequencies (> or = kHz). Lack of data, especially at higher frequencies, prevents a definitive statement from being made as to the feasibility of this acoustic application.
