Development and sea trial of the parametric sub-bottom profiler system for autonomous underwater vehicles-off Hatsushima Island-

摘要

The exploration of buried deposits under the sea sediment requires high directivity and low attenuation beams. The parametric sub-bottom profiler meets these requirements; moreover, it is comparatively small and can be easily mounted on autonomous underwater vehicles (AUVs). For this reason, we are developing a new PSBP system for AUVs. This paper presents the recent results of the PSBP system for AUV during the sea trial conducted under the “Zipangu of the Sea” Project as a sub-program of SIP (Strategic Innovation Promotion), managed by the Cabinet Office of the Japanese government.
