Beam Steering Unit
Beams are formed by shifting the phase of the signal emitted from radiating elements, to provide constructive/destructive interference so as to steer the beams in the desired direction.
Beamforming
What is beamforming?
- A signal processing technique used in sensor arrays for directional signal transmission or reception
- Can be used at both the transmitting and receiving ends
- Can be used for radio or sound waves
Beam Steering
What is beam steering?
- changing the direction of the main lobe of a radiation pattern.
Beam Steering Unit
- In radio systems, beam steering may be accomplished by switching the antenna elements or by changing the relative phases of the RF signals driving the elements.
BEAM
What is a beam?
- a ray or shaft of light
- a constant directional radio signal transmitted for the guidance of pilots
- the course indicated by a radio beam
Wide Beam Lobe - usable for searching
Narrow Beam Lobe - more accurate
The main beam always points in the direction of the increasing phase shift. Well, if the signal to be radiated is delivered through an electronic phase shifter giving a continuous phase shift then the beam direction will be electronically adjustable. However, this cannot be extended unlimitedly. The highest value, which can be achieved for the Field of View (FOV) of a olanar phased array antenna is 120° (60° left and 60° right).
