What is beam scan?

Beam scanning is a technique used in radar and communication systems to direct and focus a signal in a specific direction, typically by electronically adjusting the phase and amplitude of the signal from an array of antennas. This allows for rapid changes in the direction of the beam without physical movement of the antennas, enabling improved tracking and targeting capabilities. Beam scanning enhances the system's ability to detect and follow moving objects while reducing interference from unwanted signals. It is commonly applied in applications such as radar, satellite communications, and wireless networks.
