BII7630 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.
