<p>PURPOSE:To find a school of fishes from the ground and investigate the state of the sea bottom by mounting an underwater camera operated by wireless control on an unattended buoy capable of moving and stopping by wireless control. CONSTITUTION:A battery, an underwater camera operated by wireless control and a wireless installation for a directional mark are mounted on a buoy capable of moving and stopping by wireless control and the image of the underwater camera is observed by an industrial television on the ground. The position of the buoy is found by receiving a radio wave from the wireless installation for the directional mark at two points on the ground. An underwater microphone is attached to the buoy to monitor sounds and thereby the navigation of ships and submarines can be caught.</p> |
