Ocean microwave communication system

To assure submarine coaxial cable system reliability in shallow water areas, an original ocean microwave communication system featuring a large floating ocean station (135m length, 100m draft)has been developed. This floating station is a cylindrical, vertical buoy moored to the bottom of a continental shelf and operates as a jointing point between the deep sea submarine cable system and the ocean microwave radio system. This paper discusses specific problems and solutions pertinent to establishing this 23,000 channel-capacity communication system, such as smaller sized antennas and radio equipments, new modified monopulse tracking system and high speed space diversity system. An ocean test using the first model of the floating station is planned for this summer.
