A compensation unit compensates for a Doppler shift of the reception signal on the basis of a possibility of a change amount of the Doppler shift. A search unit changes a value of a possibility of the change amount of the Doppler shift in a case where a bandwidth having a power equal to or greater than a predetermined threshold in frequency components of the reception signal after the compensation is larger than a predetermined value.
