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.
