浅海用マルチビーム測深システム(SEABAT9001S型)の改善

抄録

The development of technology in electronics, communications and measurements with digital equipment have spawned a lot of new measuring techniques in the fields of researches and thus the conventional research techniques will be replaced by the new ones.
Concerning the fields of seafloor topography survey, narrow-multibeam echosounders designed for shallow water have been used in Japan since 5 years ago. This equipment enabled us to obtain bathymetric information in large features at one time more precisely compared with the conventional equipment which obtains seafloor topography as a collection of depths data measured at numerous points. In addition, GPS enabled us to obtain real-time information of its position anywhere on the globe with great precision in three dimensions. Consequently more discoveries in the fields of marine science will be made from the information of the more detailed seafloor topography.
This paper will describe some ways to improve the narrow multibeam echosounder system designed for shallow water (SEABAT9001S, Reson) which we, Kokusai Kogyo Co., Ltd., have been working on, and its future prospects.
