A radio receiving apparatus includes a detection unit and a directivity
changing unit. The detection unit detects an occurrence of
intermodulation interference to a desired signal demodulated based on
received signals received by a plurality of antenna elements. The
directivity changing unit changes a reception directivity pattern of the
plurality of antenna elements to another pattern having a null direction
different from a null direction obtained before the directivity pattern
is changed, in accordance with detection of the occurrence of the
intermodulation interference by the detection unit.
