Range-Angle-Dependent Beamforming by Frequency Diverse Array Antenna [PDF]
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 ...

Frequency Diverse Array and Spotlight Synthetic Aperture Radar 2D Imaging Based on Multiple Repeated Subpulses [PDF]
SensorsFrequency diverse array (FDA) beams show an “S” shape in space and cannot form a spot beam; thus, they cannot be directly combined with spotlight synthetic aperture radar (SSAR).

Ambiguity Analysis for Multitarget Estimation Using Random Permutated Frequency Diverse Arrays
IEEE Access, 2020 For multitarget estimation using a frequency diverse array with a random permutated frequency increment (RP-FDA), ambiguity occurs when targets are located at specific locations and the frequency increment vector is not properly designed.
