Abstract: This application discloses signal processing methods and apparatuses, in the field of radar technologies, and may be applied to scenarios such as intelligent transportation (for example, intelligent transportation, assisted driving, or autonomous driving), a smart home, and a robot. In an example method, a first range time-domain signal of a first subband and a second range time-domain signal of a second subband adjacent to the first subband are obtained. The first range time-domain signal and the second range time-domain signal are synthesized and superposed to obtain a third range time-domain signal. A first peak point and a second peak point of the third range time-domain signal are obtained. A constant phase error θerr between the first range time-domain signal and the second range time-domain signal is obtained based on the first peak point and the second peak point.
