PHASE-CONTROLLED ARRAY SYSTEM AND BEAM SCANNING METHOD

摘要

Provided are a phase-controlled array system and beam scanning method. The phase-controlled array system comprises at least two wave antennas (21) arranged in parallel. Each wave antenna (21) comprises at least two antenna units (22) sequentially connected. A first end (23) of each wave antenna (21) connects to and utilizes a corresponding first radio-frequency channel (20) to connect with a signal processing module (24) of the phase-controlled array system. By adjusting a configuration of the first radio-frequency channel (20), a phase and/or an amplitude of a signal inputted to the signal processing module (24) from the first end (23) of the wave antenna (21) can be adjusted. The phase-controlled array system and beam scanning method reduce the number of radio-frequency channels required w realizing spatial beam scanning, thereby reducing complexity and costs of the phase-controlled array system.
