Abstract

This paper presents a modified version of a true time delay, broadband nulling approach to beamforming for a linear antenna array. The approach begins with the well known Davies method of narrowband beamforming; alters it to include time delays via tunable lasers and high dispersion optical fiber; and finally modifies the Davies tree itself to resemble decomposition filters from wavelet theory. This last modification cuts the required number of tunable lasers for an N element array but also decreases the number of independent null.
