1. A radio detection and ranging (radar) signal processing method, comprising:
obtaining a beat frequency signal based on a chirp signal of a radar transmission signal generated based on a frequency modulation model and a radar reflection signal obtained from the radar transmission signal being reflected from an object; and
generating radar data by normalizing a phase change between the beat frequency signal and another beat frequency signal based on a change in a carrier frequency of the chirp signal, such that the phase change is a same value at each of a plurality of sampling points of the chirp signal.
