LARS Tech Report Number



An experiment is described in which aircraft scanner data from calibrated reflectance panels in the scene was used to calibrate the scanner data for nearby targets. The method used permits reflectance calibration of scanner data for areas which are in environmental proximity to the reflectance panels. That is, the calibration is valid for areas receiving the same illumination, from the same sun angle and for the same aircraft altitude. Atmospheric condition changes, cloud cover changes, different sun angles, and other environmental factor changes will alter the calibration and render the panel reference parameters invalid. The method described here is experimental and is disclosed for the use of LARS researchers wishing to experiment with estimation of approximate reflectance data even though it includes the variances caused by the environmental factors.
