Abstract

A distance measuring method and apparatus are provided. The distance measuring apparatus emits a transmission signal while changing a frequency over time, receives a reception signal from an object in response to the transmission signal being reflected from the object, samples a beat frequency indicating a difference between a frequency of the transmission signal and a frequency of the reception signal in a sampling range that changes based on the beat frequency, and determines a distance to the object based on the sampling.
