1. An antenna receiver comprising:

  • a plurality of mixers that frequency-converts signals received by a plurality of antennas into intermediate-frequency signals;

    a plurality of local oscillators, which correspond to the plurality of mixers and which supply local oscillation signals having the same frequency to the mixers;

    a plurality of PLL circuits, which correspond to the plurality of local oscillators and which set the frequency of the local oscillation signals; and

    an adder that adds the intermediate-frequency signals output from the mixers, wherein phases of reference signals supplied to the PLL circuits are independently changeable from each other.
