Spectral And Radiometric Calibration Of The Airborne Visible/Infrared Imaging Spectrometer

Abstract

The laboratory spectral and radiometric calibration of the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) used in the radiometric calibration of all AVIRIS science data collected in 1987 is described. The instrumentation and procedures used in the calibration are discussed and the calibration accuracy achieved in the laboratory as determined by measurement and calculation is compared with the calibration requirements. Instrument performance factors affecting radiometry are described. The paper concludes with a discussion of future plans.
