| Abstract: | In order to detect underwater objects such as submarines, an underwater acoustic source is required, with its frequency in the range of 1-4 kHz, and the pressure peak of the acoustic pulse more than 1 MPa. This kind of acoustic pulse can be generated by the means of large current pulse discharge under water. This paper describes the development of this kind of acoustic pulse generator. This type of pulsed power acoustic source has many advantages over the others, it has great potential in millitary application. |
