Abstract

The power output and thus the range of sonar apparatus is limited by caviion of the water surrounding a sonar transducer at high output power levels. The invention "strengthens" the water surrounding a sonar transducer by increasing the hydrogen content to permit a many fold increase in the transducer output power before cavitation occurs.
