Abstract
An analysis is conducted to determine the feasibility of using a buried sonar transducer to echo-locate torpedoes imbedded in sediment. The active sonar equation is examined and representative values for each term are developed which are appropriate for the sediment on the acoustic test ranges at the Naval Undersea Weapons Engineering Station, Keyport, Washington. It is found that transmission loss through the sediment limits the useful range of the proposed 10 kHz active sonar system to approximately 10 meters, thus rendering it impractical as a localization tool. Three alternative systems are proposed for further consideration.
