Underwater Acoustic Transceiver

BII7640 Series Underwater Dual-Element Transceiver: Communication

BII underwater acoustic transceivers are dual-element transducers which integrate (1) a broadband omnidirectional projector in horizontal plane and an omnidirectional low noise receiver in horizontal and vertical planes, (2) a broadband omnidirectional projector in horizontal plane and a directional low noise receiver in vertical plane, or, (3) a broadband omnidirectional projector in horizontal plane and a broadband directional projector in vertical plane. Typical applications include artificial acoustic target which is able to simulate quantitatively the noise, Doppler effect, echo or characteristic sounds of the subjects such as ships, torpedoes, submarines, fish, marine animals, seabed, sub-bottom, etc.

Typical Applications
Artificial Acoustic Target: Echo-Repeater Target, Active-Acoustic Target. Underwater Communication and Modem, Acoustic Release. Underwater Acoustic Positioning: Transponder, Responder.	Underwater Telephone, Long Range Sound Transmission. Acoustic Deterrent to Marine Animals Marine. Animal Behavior Research, Bioacoustic Stimuli & Playback.
