Hyperspectral Microwave Radiometer for Airborne Atmospheric Sounding

We present here the on-going design of a hyperspectral radiometer called HyperSounder operating near two Oxygen absorption lines at 60 and 118 GHz, and the water vapor absorption line at 183 GHz for airborne atmospheric sounding. This radiometer is designed to be installed onto a Gulfstream V (G550) aircraft operated by the National Oceanographic and Atmospheric Administration’s (NOAA) Office of Marine and Aviation Operations (OMOA). The key enabling technology used in this instrument is fast sampling ASIC based spectrometer chipsets that allow for wide-band width and high resolution signal detection.
