Digital Beamforming for Antenna Arrays

2019 IEEE Indian Conference on Antennas and Propogation (InCAP), 2019
With an increasing number of subscribers to the terrestrial cellular and/or satellite based services, and a resultant rise in the demand for the data rate, there is an urgent need of advanced signal processing schemes that improve the power and the spectral efficiencies. Digital beamforming using an array of antenna elements is one such technique. When

Digital Beamforming in the Frequency Domain

The Journal of the Acoustical Society of America, 1969
A recent proposal to use digital Fourier transformation in forming acoustic beams is discussed tutorially. Relations to other procedures for beamforming, and for spectral analysis, are given. Need is shown for a lower limit on the data batch size.

Digital beamforming-an emerging technology

MILCOM 88, 21st Century Military Communications - What's Possible?'. Conference record. Military Communications Conference, 2003
The current status of digital beamforming (DBF) technology is reviewed. Particular attention is given to the advantages of DBF, including improved adaptive pattern nulling, superresolution, self-calibration, and array element pattern correction. DBF implementation is examined, and examples of DBF systems are mentioned. >

Digital beamforming receiver technology

International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990
A recent digital beamforming (DBF) receiver module effort is described. Each individual receiver module is divided into four mechanical packages. The element submodule is in stripline and contains the radiating element, C-band filtering, and calibration signal coupling functions.

Digital Beamforming and Adaptive Processing

2019
Modern ESAs present the opportunity to do digital processing on the outputs of multiple subarrays without having to digitally sample the output of each element, thereby greatly simplifying the design of the ESA while still achieving the benefits of adaptive processing.
