Radio Receiver and Radio Receiving Method

The present invention is directed to the provision of a radio receiver and of a radio receiving method that can reliably detect IBOC hybrid broadcast carrier waves. The radio receiver includes a tuning section for tuning to the frequency of a broadcast carrier wave, a detection section for detecting the signal level of the broadcast carrier wave at the frequency to which the tuning section has tuned, and a control section for detecting an IBOC hybrid broadcast carrier wave, based on a first signal level detected by the detection section by causing the tuning section to tune to a first frequency, a second signal level detected by the detection section by causing the tuning section to tune to a second frequency, and a third signal level detected by the detection section by causing the tuning section to tune to a third frequency. The radio receiving method is implemented in such a radio receiver.
