Doppler shift compensation apparatus and doppler shift compensation method

A Doppler shift compensation device comprising one or more processors configured to perform as:

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