Abstract
A method for vicarious spatial characterization of a remote sensor system. The method includes detecting, via the remote sensor system, radiation reflected from at least one body of water corresponding to a plurality of point reflector images, selecting a set of point reflector images from the plurality of point reflector images, the selected set of point reflector images corresponding to sub-pixel point reflector images, analyzing the selected set of point reflector images by executing an algorithm for fitting the point reflector images to obtain a point spread function of the remote sensor system, and determining a spatial characteristic of the remote sensor system based on the point spread function.
