Digital beamforming in a large conformal phased array antenna for satellite TT&C — Demonstration

This paper presents the design, development, theoretical and measured results of Digital Beam Forming (DBF) hardware for use with a large, multi-beam conformal phased array antennas such as the Geodesic Dome Phased Array Antenna (GDPAA) shown in Figure 1[1]. The GDPAA system with DBF on receive can provide multiple simultaneous links for satellite tracking, telemetry, and command (TT&C) functions including adaptive pattern control for anti-jamming or interference suppression, and high resolution direction finding.
