PROBLEM TO BE SOLVED: To provide a radio communication device capable of correctly measuring distance between radio communication terminals, even when transmission power of a signal transmitted from a transmitter fluctuates.SOLUTION: A radio communication device 10 comprises: a transmission unit 11 for transmitting first and second radio signals to a searched device 20; a reception unit 12 for receiving information on reception strength of the first and second radio signals measured by the searched device 20, from the searched device 20; and a processing unit 13 for detecting fluctuation in distance from the searched device 20 depending on the reception strength of the first and second radio signals. The processing unit 13 determines whether or not transmission strength of the first radio signal is different from that of the second radio signal; and corrects the reception strength of at least either of the first and second radio signals by using transmission strength difference between the first and second radio signals, when the transmission strength of the first radio signal is different from that of the second radio signal. |
