Abstract
A calibration device includes reference signal normalizing units-to-M that set, as a reference signal, a frequency domain signal being associated with either one 2 of reception antennas and being included in frequency domain signals obtained by conversions made by Fourier transform units-to-M, and divide the frequency domain signals after the conversion made by the Fourier transform units-to-M by the reference signal, thereby normalizing the frequency domain signals, and reference frequency normalizing units-to-M that normalize the frequency domain signals normalized by the reference signal normalizing units-to-M by using a signal having a reference frequency included in the frequency domain signals.
