Abstract: A method of determining an elevation angle of a target object includes determining a first elevation angle with respect to the target object based on a first component of an initial radar signal received through an array antenna of a radar sensor, determining an angular window based on the first elevation angle, generating a second direction of arrival (DOA) estimation spectrum by applying the angular window to a first DOA estimation spectrum generated based on a second component of the initial radar signal, and determining a second elevation angle with respect to the target object based on the second DOA estimation spectrum.
