| This thesis describes of development and analysis leading to concept designs of a blackbody simulator for ultra high accuracy ground calibration and a blackbody simulator for drift correction. Both blackbody simulators will be used for the National Aeronautical and Space Administration's (NASA) Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) project.;The first, a large aperture, cylindro-cone blackbody simulator, must have an unprecedented radiometric uncertainty of less than 1% over a wavelength range of 1.2 to 17.0 ;The In-Flight Calibrator (IFC) blackbody simulator will be used for periodic checks during instrument operation to correct for drift in calibration. This blackbody simulator is designed to have a mass of 0.1 kg with a change in instrument response of less than 1% over the mission lifetime. |
