phased array

[fāzd]
an array transducer assembly that has very thin rectangular elements arranged side by side. It relies on electronic beam steering to sweep sound beams over a sector-shaped scanned region. Beam steering is done by using electronic time delays in the transmitting and receiving circuits.
