phased array

phased array

 (fāzd)
n.
An arrangement of dipoles on a radar antenna, in which the phase of each dipole is controlled by a computer so that the beam can scan very rapidly.

phased array

n
(Astronomy) an array of radio antennae connected together to form a single antenna. The beam produced can be steered across the sky by adjusting the phases of the signals. The absence of moving parts enables the beams to be steered very rapidly, making it useful in radar
