Abstract1The spark gap underwater sound transducer is a 50-year-old technology which was studied at length during the late 1950's, principally by Edgerton at MIT and by Caulfield at the Woods Hole Oceanographic Institution. Originally it was intended as a low-frequency sound source for sub-bottom seismic exploration. In Phase I, the spark gap transducer will be studied, analyzed and converted from a seismic transducer to a transducer more suited for compact-size low-frequency sonar applications. This will be accomplished by integrating the spark gap source with mechanical or hydraulic resonators or wave filters. A breadboard model will be constructed and tested.
