1. A communication apparatus comprising:
an acquisition unit configured to acquire a delay profile for a first transmit signal from a transmitting apparatus; a determination unit configured to determine a start time at which to start detection of a second transmit signal from the transmitting apparatus and an end time at which to end the detection of the second transmit signal from the transmitting apparatus, based on the delay profile; a forming unit configured to control a plurality of antennas and form a predetermined antenna directivity characteristic, wherein the forming unit forms an antenna directivity characteristic that has a beam peak at a predetermined angle; a detection unit configured to detect a reception intensity of the second transmission signal from the transmitting apparatus; a control unit configured to control the detection unit such that the detection unit operates during a period between the start time and the end time that are determined by the determination unit, and does not operate at other times; and a selection unit configured to select an angle at which the reception intensity detected by the detection unit exceeds a predetermined intensity. |
