Abstract
A method of integrating a detected signal along a given angle of arrival to improve detection. The method includes receiving the signal at a first antenna, receiving the signal at a second antenna, generating a phase difference trajectory based on the signal from the first antenna and the signal from the second antenna, and extracting a signal by integrating the phase difference trajectory over frequency for a plurality of angles of arrival.
