Range-Angle-Dependent Beamforming by Frequency Diverse Array Antenna
International Journal of Antennas and Propagation, 2012 This paper proposes a range-angle-dependent beamforming for frequency diverse array (FDA) antenna systems. Unlike conventional phased-array antenna, the FDA antenna employs a small amount of frequency increment compared to the carrier frequency across ...
