Development of Next-generation Millimeter-wave Components and Subsystems for Remote Sensing of Atmospheric Thermodynamic Profiles
Recent developments in low-noise, wide-bandwidth MMIC amplifiers from 90-180 GHz have enabled the increased use of wideband atmospheric windows between absorption lines. At Colorado State University, in collaboration with the Caltech Jet Propulsion Laboratory, critical millimeter-wave antenna and receiver technologies are under development to enable low-mass, small-volume, low-cost radiometers aboard future Earth science satellite missions. In addition to improving the accuracy of weather forecasts, both ground-based and satellite measurements are planned for synergistic use with synthetic aperture radar interferometers in order to correct for changes in propagation speed of radar pulses due to fine-scale water vapor variability. These developments are expected to improve monitoring of ocean surface topography and circulation, inland water hydrology, earthquakes and landslides, as well as digital elevation mapping.
