水中超音波を用いたダイビング支援システムの開発

抄録

In this research, we develop a diving support system for the purpose of supporting safety measures for the diving experience. Radio waves are highly attenuated in water, making it difficult to communicate. Therefore, communication is performed using ultrasonic waves, which have less attenuation than radio waves. In this paper, we propose an inexpensive voice transmission system and an acoustic positioning system as support systems. In the voice transmission system, voice transmission is performed between divers on the ground and underwater. In the acoustic positioning system, the position is estimated assuming that it will be mounted on a diver or an underwater drone.
