New towed transducer concept

Abstract

The history of towed transducer applications at the Institute of Marine Research, Bergen, is reviewed. Advantages and disadvantages of several designs are summarized. To improve performance significantly, a new system design is proposed. This entails constant immersion of the towed body, either hydraulically locked in a recess in the hull or in tow. The merits of being able to use the same transducer in both configurations are emphasized.
