Paper Abstract

Helicopter-based spectral radiance measurements over several homogeneous ground targets were performed with a portable calibrated spectrometer covering the wavelength region 400- 1000 nm. The flight altitude was varied from 200 to 1000 m and radiance spectra were collected in altitude steps of 200 m. Up to 20 spectra were collected for each flight level to evaluate average and standard deviation for homogeneity. For the grass and concrete target, ground reflectance measurements were performed shortly before and after the airborne radiance spectra were acquired. Meteorological data from a local DLR weather station is used as input for the MODTRAN radiative transfer code. The measurements of airborne radiance spectra are intended to support the inflight calibration of the hyperspectral DAIS sensor. Results of measured and modeled radiance spectra are presented and discussed.
