Abstract

For the correct quantitative usage of a remote sensing imaging instrument, a complete characterization of the instrument is necessary. Besides the standardly used calibration factor and spectral sensitivity curve, one also needs the knowledge of the function which describes the spatial sensitivity of the instrument: the Point Spread Function (PSF). Ideally this function should be measured prior to launch. Alternatively, a model based approximation for the PSF can be calculated. This is illustrated for the Scanning Radiometer for radiation Budget studies (ScaRaB) instrument broadband channels.
