Application Technology of Adaptive Beam-forming in Radar Side-lobe Anti-Interference

Radar systems play an important role in modern military and civilian systems, but radar signals are often affected by side-lobe interference during spatial transmission. Side-lobe interference refers to the interference of signal energy received by the side-lobes of the radar main lobe beam pattern, which affects the detection of radar echo signals by the main beam. Adaptive beamforming, as an effective anti-interference method, can effectively reduce the impact of side-lobe interference by dynamically adjusting the beam pattern. This article provides some reference for the engineering practice of adaptive beam-forming in radar receiving systems through simulation of adaptive digital beam-forming algorithm, QR decomposition, diagonal loading and other algorithms.
