Abstract
The present invention provides a radio communication apparatus that does not need installation of multiple radio devices in a communication node and requires only a single radio device to construct a data link of any of line-of-sight communication, over-the-horizon communication and aerial-vehicle communication. A radio communication apparatus includes a line-of-sight communication processing part that controls a beam from a phased array antenna to establish a line-of-sight communication, which is used when there is no obstacle in a radio transmission channel, an over-the-horizon communication processing part that controls the beam from the phased array antenna to establish an over-the-horizon communication, which is used when there is an obstacle in the radio transmission channel, and an aerial-vehicle communication processing part that controls the beam from the phased array antenna to establish an aerial-vehicle communication, which is used for communication with a communication node on a flying object, and the phased array antenna switches among the line-of-sight communication, the over-the-horizon communication and the aerial-vehicle communication.
