  • Publication number: 20240145911
    Abstract: An antenna correcting system is provided. The antenna correction system compares amplitudes of antenna signals that are emitted or received respectively by a plurality of antenna units with each other to select one of the amplitudes as target amplitude. The antenna correction system corrects the amplitude of each of the antenna signals according to the target amplitude. As a result, the amplitudes of the antenna signals are the same as each other or approximate to each other. After the amplitudes of the antenna signals are corrected, the antenna correction system compares phases of the antenna signals with each other to select one of the phases as a target phase. The antenna correction system corrects the phase of each of the antenna signals according to the target phase. As a result, the phases of the antenna signals are the same as each other or approximate to each other.
