Abstract
Deep sea manned submersible is a key technology for deep sea exploring and exploitation. Chinese “Jiaolong” is the deepest one among manned submersible on duty around the word. The functions of Jiaolong’s acoustic system include underwater communication, positioning, obstacle avoidance, target searching, high resolution bathymetric scanning, etc. Its advanced high speed underwater acoustic communication system can transmit images, data, text, voice and Morse codes, and its advanced high resolution bathymetric side scan sonar can acquire high resolution 3D map of the sea bottom. The overall performance of Jiaolong acoustic system is superior to any other manned submersible. In future, manned submersible acoustic system will develop to full ocean depth, higher underwater communication capability, higher navigation and position accuracy, more measurement functions and modules. And for China, acoustic technologies and instruments will be localized.
