Measurement of Torpedo Running Self-Noise under Active Homing Mode

The effect of reverberation makes it very difficult for a torpedo to acquire its self-noise under active homing mode, therefore, a measurement method of torpedo self-noise with reverberation during torpedo running under active homing mode is presented in this paper. The principle of the method is introduced, and computations are conducted. Experimental result verifies its feasibility. Both the noise received by transducer elements and the noise in transmitted beams can be measured by this method with flexibility, real-time, and low cost. And the self-noise while performing the task of torpedo trial can also be measured by this method.
