ABSTRACT:
A radio-frequency receiver device including receiver antenna elements each arranged to receive a signal from a desired communication object, a phased-array control portion to perform a phased array antenna control for controlling the directivity of reception of the signals by the receiver antenna elements, an adaptive-array control portion to perform an adaptive array antenna control for controlling the directivity of reception of the signals by the receiver antenna elements, a received-signal-quality determining portion to determine whether the signals received by the receiver antenna elements has a quality higher than a predetermined threshold, and a directivity control switching portion configured to enable the phased-array control portion to perform the phased array antenna controls, and to enable the adaptive-array control portion to perform the adaptive array antenna control only if a negative determination is obtained by the received-signal-quality determining portion after the phased array antenna control.
