Phased Array Transducer
BII-7630 Series Phased Array Transducer: Beamforming
BII's phased array transducers are rectangular (linear) or curved array
(Cylindrical Sector) with custom-fit
along-length (or along-curve) beamwidth and cross-length (or
cross-curve) beamwidth for use in
location, search of sound sources underwater in in tens or
hundreds meter range, and acoustical imaging in biomedical,
oceanography, NDT and material study. Along-length (or along-curve) beam
can be steered and focused in
±90º range with array beamforming technology.
Multiple beams at different directions can also be formed
simultaneously with digital beamforming technology. The side lobes
along length can be suppressed with amplitude shading or weighting.
Two or four array hydrophones can be used to set up "T" or "+" type cross
array functioning as Target Angle Estimation
System with Mills Cross technique. A phased line array transducer
(projector) and a phased array hydrophone can work as a multibeam
SONAR with Mills Cross technique. Multiple transducers can be wired in parallel electrically to
set up a longer line array for reducing along-length beam width in
low frequency range.
