Parametric localisation in frequency diverse array [PDF]
IET Radar, Sonar & Navigation, 2020 The authors present a non‐traditional, parametric method for velocity, angle, and range estimation in a frequency diverse array radar. Unlike the traditional beamforming techniques, the proposed scheme transmits an omni‐directional sinusoid regardless of the target locations.

Index Modulation for Frequency Diverse Array [PDF]
IEEE Antennas and Wireless Propagation Letters, 2020 The index modulation (IM) approach adds an extra signal modulation dimension by utilizing a subcarrier index domain, which is in addition to the traditional IQ domain. A frequency diverse array (FDA) technology is rapidly developing as a new technique for radar systems.

Impacts of frequency increment errors on frequency diverse array beampattern [PDF]
EURASIP Journal on Advances in Signal Processing, 2015 Different from conventional phased array, which provides only angle-dependent beampattern, frequency diverse array (FDA) employs a small frequency increment across the antenna elements and thus results in a range angle-dependent beampattern. However, due to imperfect electronic devices, it is difficult to ensure accurate frequency increments, and ...
