A Computer Program for Infrared System Analysis

Abstract : A computer program is presented which calculates the effective irradiance received by a remote optical sensor from an arbitrary radiating source. The analysis includes the effects of atmospheric absorption, receiver relative response, and source distance. The spectral range considered is 3.7 to 5.0 microns. The program utilizes an atmospheric transmission model accounting for water vapor, carbon dioxide, and nitrous oxide, and is written for the basic IBM 1620 computer. (Author)
