Abstract: A method with three-dimensional (3D) position measuring using a radio detection and ranging (radar) sensor includes: transmitting, through the radar sensor, a transmission signal of which a carrier frequency varies over time; obtaining, through the radar sensor, a reflected signal from the transmission signal being reflected by an object; obtaining a beat frequency signal indicating a frequency difference between the transmission signal and the reflected signal; and estimating 3D position information of the object based on groups of sample data of different frequency bands extracted from the beat frequency signal.
