ABSTRACT:
A communication system for obtaining predetermined information from an underwater terminal via a sonobuoy is provided. The system includes an underwater terminal for transmitting and receiving sound wave signals, a base station apparatus for transmitting and receiving radio wave signals, and a plurality of sonobuoys for transmitting and receiving the sound wave signals to and from the underwater terminal, and for transmitting and receiving the radio wave signals to and from the base station apparatus.
