Claim 10:
11. A remote sensor system configured to provide imaging for airborne and/or space-based applications, the remote sensor system comprising:
an electro-optical/infrared (EO/IR) sensor configured to detect radiation reflected from a body of water;
a receiver configured to receive a plurality of point reflector images corresponding to the radiation detected by the EO/IR sensor; and
a processor coupled to the receiver and configured to:
select 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;
analyze 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
determine a spatial characteristic of the remote sensor system based on the point spread function.
