The present technology relates to a signal processing device, a signal processing method, a program, and an information processing device capable of reducing processing of folding correction of velocity measured by a radar. The signal processing device includes a measurement unit that measures, on the basis of an output signal from a radar, a distance and relative velocity of a reflector that reflects a transmission signal from the radar, and a correction unit that performs folding correction of measured velocity of the reflector on the basis of correlation between a measured distance and measured velocity of the reflector at a certain measurement time, and a measured distance and measured velocity of the reflector at a time before the measurement time. The present technology can be applied to, for example, a system that senses an object around a vehicle.
