Paper Abstract

In-flight calibration of space-based imaging radiometers is essential to allow corrections for changes in instrument response that occur during storage on ground, launch and operation in space. The most serious technical problems are in calibration for absolute spectral response in the waveband of reflected solar radiation -- visible through short-wave IR. Some concepts for in-flight calibration are presented, that are applicable mainly to hyperspectral instruments used for remote sensing at moderate spatial resolution. Stress is placed on confidence levels that can be achieved, using on- board systems of minimal complexity. The main objective is to record ideas for review in future development programs, with some analysis of their merits.
