UAVSAR: a new NASA airborne SAR system for science and technology research
Paul A. Rosen,S. Hensley,K. Wheeler,G. Sadowy,T. Miller,S. Shaffer,Ronald J. Muellerschoen,Cathleen E. Jones,Howard A. Zebker,Soren N. Madsen +9 more
TL;DR: In this article, a reconfigurable, polarimetric L-band synthetic aperture radar (SAR) is designed to acquire airborne repeat track SAR data for differential interferometric measurements.
Journal ArticleDOI
The Glacier and Land Ice Surface Topography Interferometer: An Airborne Proof-of-Concept Demonstration of High-Precision Ka-Band Single-Pass Elevation Mapping
Delwyn Moller,Scott Hensley,G. Sadowy,Charles D. Fisher,Thierry Michel,M. Zawadzki,Eric Rignot +6 more
TL;DR: Initial results indicate that the Ka-band cross-track interferometric synthetic aperture radar will exceed its system requirements, including systematic calibration, due to penetration of the electromagnetic waves into the snow cover.
Proceedings ArticleDOI
Next generation millimeter-wave radar for safe planetary landing
Brian D. Pollard,G. Sadowy +1 more
TL;DR: In this paper, the authors identify the fundamental issues within each approach, at arrive at strawman sensor designs at a center frequency at or around 160 GHz (G-band) and find that a G-band radar velocimeter design is capable of sub-10 cm/s accuracy, and a g-band imager with sub-0.5 degree resolution over a 28 degree field of view.

Journal ArticleDOI
A Class-E Tuned W-Band SiGe Power Amplifier With 40.4% Power-Added Efficiency at 93 GHz
Peter Song,Michael A. Oakley,A. Cagri Ulusoy,Mehmet Kaynak,Bernd Tillack,G. Sadowy,John D. Cressler +6 more
TL;DR: In this article, a W-band power amplifier with Class-E tuning in a SiGe BiCMOS technology is presented, which is enabled by the cascode topology, low upper base resistance, and minimally overlapping current-voltage waveforms.
