Calibration of the Japanese Earth Resources Satellite-1 optical sensor using the Airborne Visible/Infrared Imaging Spectrometer

摘要

Abstract: In this paper, we describe an experiment to calibrate the Optical Sensor on board the Japanese Earth Resources Satellite-1 with data acquired by the Airborne Visible/IR Imaging Spectrometer. 27 August 1992 both OPS and AVIRIS acquired data concurrently over a calibration target on the surface of Rogers Dry Lake, Nevada. The high spectral resolution measurements of AVIRIS were convolved to the spectral response curves of the OPS. These data, in conjunction with the corresponding OPS digitized numbers, were used to generate the radiometric calibration coefficients for the eight OPS bands. This experiment establishes the suitability of AVIRIS for the calibration of space-borne sensors in the 400-2500 nm spectral region. !7
