- 論文の詳細を見る
A deep-sea unmanned vehicle "Kaiko," which can be used under water to a depth of 11,000 m, is equipped with a side scan sonar newly developed for underwater topographic survey and searching for lost objects. The side scan sonar features a tilted arrangement transducer array for suppressing grating lobes. The driving frequency on the port side is 38 kHz, and that on the starboard side is 42 kHz. The source beam width in the longitudinal direction is 2° and that in the transverse direction is 50°. In 1999, objects lost underwater were located using the side scan sonar, and fallen rocket parts as large as several meters could be found in a range of about 1 km.
