In
phased array antennas can electronically steer the beam, changing the angle of the boresight by shifting the relative phase of the radio waves emitted by different antenna elements, and even radiate beams in multiple directions (multiple boresights).[1]
The term boresight came from
high-gain antennas such as parabolic dishes, which produce narrow, pencil-shaped beams which are difficult to aim accurately at a distant receiving antenna. These often are equipped with optical boresights
to assist in aiming.
