Abstract
A signal acquisition unit acquires a reception signal received by a reception device from a transmission device that moves relative to the reception device. A bandwidth specifying unit specifies a reception bandwidth that is a bandwidth of the reception signal. A shift specifying unit specifies a change amount of a Doppler shift per time on the basis of a difference between a bandwidth of a transmission signal in the transmission device and the reception bandwidth. A compensation unit compensates for a change of the Doppler shift of the reception signal on the basis of the change amount specified.
