Frequency Diverse Array with Cubic Sinusoidal Frequency Offset
Journal of Physics: Conference Series, 2020 Abstract Frequency diversity array radar (FDA) has range-angle dependent beampattern, providing enormous potential for the application of this new type of radar. However, the beampattern of conventional FDA (CFDA) has two problems: range-angle coupling and range periodicity, limiting the application of FDA.

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 ...
