Advances in digital calibration techniques enabling real-time beamforming SweepSAR architectures

Hoffman, James P. / Horst, Stephen / Perkovic, Dragana / Shaffer, Scott / Ghaemi, Hirad / Veilleux, Louise

Real-time digital beamforming, combined with lightweight, large aperture reflectors, enable SweepSAR architectures, which promise significant increases in instrument capability for solid earth and biomass remote sensing. These new instrument concepts require new methods for calibrating the multiple channels, which are combined on-board, in real-time. The benefit of this effort is that it enables a new class of lightweight radar architecture, Digital Beamforming with SweepSAR, providing significantly larger swath coverage than conventional SAR architectures for reduced mass and cost.
