DOI: 10.1109/lsp.2021.3128317
Abstract: Beampattern synthesis of frequency diverse arrays (FDAs) has recently raised increased attention attributed to their range-dependent beampattern. The transmit beampattern of uniform FDA appears $S$-shaped, which implies coupling in the range-angle domain and thus causing… read more here.
