Description

technical field [0001] The invention relates to the technical field of active phased array radar antennas, in particular to a phased array radar antenna beam control circuit detection system and an implementation method thereof. Background technique [0002] Phased array radar, that is, phase-controlled electronically scanned array radar, uses a large number of individually controlled small antenna elements arranged into an antenna array, and each antenna element is controlled by an independent switch. The main beams with different phases (directions) can be synthesized by the time difference, and the phase can be changed in both axes. Phased array radar is divided into passive phased array radar and active phased array radar. Active phased array radar is better than passive phased array radar. Phased array radar has the advantages of flexible beam pointing, multiple independent beams can be formed at the same time, large target capacity, strong adaptability, and good anti-...
