Title:
DOPPLER SHIFT COMPENSATION DEVICE AND DOPPLER SHIFT COMPENSATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/118405
Kind Code:
A1
Abstract:
A signal acquisition unit acquires a received signal received by a receiver from a transmitter that moves relative to the receiver. A bandwidth specifying unit specifies a receiving bandwidth, which is the bandwidth of the received signals. On the basis of the difference between the transmission signal bandwidth in the transmitter and the receiving bandwidth, a shift specifying unit specifies the amount of change in the Doppler shift relative to time. A compensation unit compensates the Doppler shift change in the received signal on the basis of the specified amount of change.
