A comparative study of the computer programs GUERAP III and APART/PADE has been made based on the stray radiation analysis of a typical heat-seeking missile. The programs are compared in terms of general approaches, execution, and results. Specific areas of comparison are input requirements, information provided by each program, intrinsic uncertainties, unique program capabilities, and cost.
