| Abstract: | The pinger transducer, a core part of the bottom finding indicator, and its acoustic reflection system were introduced here. By utilizing acoustic reflection system, a high beam pattern of pinger transducer was formed in vertical direction. The directivity index of pinger transducer has 20 dB increase. By experimenting in the Pacific Ocean of the depth of more than 5 000 meter, the information of the bottom finding indication was obtained |
