Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, PROGRAM, AND INFORMATION PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/196003
Kind Code:
A1
Abstract:
This technology relates to a signal processing device, a signal processing method, a program, and an information processing device which facilitate reductions in processing for unfolding of a measured velocity by a radar. The signal processing device is provided with: a measurement unit which measures the distance and relative velocity of a reflecting body, which reflects a transmission signal from a radar, on the basis of an output signal from the radar; and a correction unit which carries out unfolding of the measured velocity of the reflecting body on the basis of a relative relationship between the measured distance and measured velocity of the reflecting body at a certain measurement time and the measured distance and measured velocity of the reflecting body prior to said measurement time. This technology can be applied, for example, to a system which detects objects around a vehicle.
