Title: Tokihiko Hamada: Innovator in Underwater Detection Technologies
Introduction
Tokihiko Hamada is a prominent inventor based in Nishinomiya, Japan. He has made significant contributions to the field of underwater detection technologies, holding a total of 2 patents. His innovative work has advanced the capabilities of sonar systems, enhancing their effectiveness in various applications.
Latest Patents
Hamada's latest patents include a forward-looking sonar and an underwater image display system. The forward-looking sonar features a transducer array divided into a first and second sub-array, along with beamforming sections that create receiving beams to capture target echoes from a wide area. This system determines the position of a target using a split-beam method, calculating both the direction and distance based on the echoes received.
The underwater detection system is designed to display underwater conditions over a large area around a ship. It utilizes a linear array type transducer and a transducer training mechanism to rotate the transducer stepwise. The system forms a receiving beam that scans a vertical cross-sectional area, storing echo signal data in an image memory. This data is then processed to produce a fractional PPI image, which is presented as a plan view of the search area around the ship.
