Original Abstract Submitted
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.
