Digital beamforming is a technology used in communication and radar systems to improve signal reception and transmission. It involves the simultaneous processing of signals from multiple antennas to form a directive beam that can be steered electronically without physically moving the antennas. This allows for better signal focusing, higher antenna gain, and improved signal quality in various applications such as satellite communications, radar systems, and wireless networks. Digital beamforming offers flexibility, adaptability, and efficiency compared to traditional analog beamforming techniques.
