Abstract
Two methods for estimating overall system resolution characteristics of the AVNIR sensor system have been investigated: The frequency domain method (Fourier transform techniques) and the spatial domain method (spatial convolution techniques). Several factors affecting estimation accuracy of the spatial characteristics method were investigated using numerical simulations. Scene structures of a knife-edge target with step edges were used with a numerical estimation procedure to predict resolution performance in advanced Earth observing satellite (ADEOS) advanced visible and near-infrared radiometer (AVNIR) imagery. The results of both methods agree closely. An effective IFOV of about 20 meters was estimated from preliminary estimation experiments for AVNIR Mu bands.
