Simulation of a Naval Research Laboratory space-based infrared surveillance sensor must include such basic effects as the time-varying geometry of the satellite-to-earth line of sight (LOS), atmospheric emission and attenuation, the optical blur of the sensor's telescope, and the noise and nonuniform response characteristics of the solid-state detectors. A user- oriented, menu-driven software, package called the End-to-End Simulation Package (EESP) has been developed to perform the necessary calculations. In addition ...
