Reduction of interference sound noise in multibeam echosounder by transmit power adjustment of multi-channel
Multibeam echosounders, newly installed on all the survey vessels of the Regional Coast Guard Headquarters in March 2014, are encountering acoustic interference from conventional multi−channel echosounders. In order to reduce this interference sound noise, we adjusted transmit power and frequencies of the multi−channel echosounders and examined its effectiveness. In this paper, we report some results of the experiments.
