BENTHOWAVE INSTRUMENT INC. Acoustic Transducer & System






BII7660 series multibeam (scanning) transducers are designed for
uses in long range 2D image Sonar, underwater floor/bottom mapping,
sector scanning, navigation, object detection, target tracking,
obstacle avoidance in hundreds and thousands meter range.
Transmitting aperture (one element) and receiving aperture (32 or 64
elements) operate independently. The curved transmitting element
transmits a broad fan-shape beam to insonify a large sector of
interest (field of view), the linear receiving array has fan-shape
beam perpendicular to the emit-beam and can be steered electrically
to scan the area of interest. Both emit and receive array are
broadband to support broadband SONAR signals (such as SINE Pulses,
FM/Chirp Pulses, Ricker Pulses, etc.). Acoustic sweeping (2D
scanning) of the horizon or vertical can be achieved with digital
beamforming technology.
Typical applications are long range acoustic positioning, tracking,
echo locating, navigation, communication, and artificial acoustic
target in horizontal or vertical plane in the ocean, rivers, and
lakes.
NOTE: BII-7660 series multibeam transducer consists of a BII7682 (curvilinear aperture) and BII7631 (linear phased array). Ordering BII-7682 and BII-7631 is recommended. Manual or mechanical scanning SONAR: BII7770 Series Underwater Mechanical Scanning Transducer.
