Abstract: A processor implement method may include determining a target azimuth angle of the target object based on an initial radar signal received through an array antenna of a radar sensor, generating a correction radar signal by correcting a phase of the initial radar signal based on the target azimuth angle, and determining an elevation angle of the target object based on the correction radar signal.

Abstract: A method includes extracting a first chirp sequence signal and a second chirp sequence signal from a radar signal, determining a first phase difference of the first chirp sequence signal based on a distance between antenna elements of the array antenna, determining a second phase difference of the second chirp sequence signal based on the distance between the antenna elements of the array antenna, determining a first direction of arrival (DOA) frequency based on a first carrier frequency based on the first phase difference, determining a second DOA frequency based on a second carrier frequency based on the second phase difference, estimating a preliminary DOA of a target based on a frequency difference between the first DOA frequency and the second DOA frequency, determining ambiguous DOA candidates, and selecting a final DOA of the target from the ambiguous DOA candidates based on the preliminary DOA.

Abstract: An object velocity detection method includes: obtaining a first reception signal and a second reception signal that are received in different time intervals through a radar sensor; determining a Doppler effect based on the first reception signal and the second reception signal; determining an angle value of an object based on a signal obtained by compensating for the Doppler effect; obtaining a compensated signal by compensating for the angle value in the second reception signal; and determining a velocity of the object based on the compensated signal.
