The Optical Signatures Program. Volume VI. Exoatmospheric Target Signatures Code (EXOSIG) User's Manual

Abstract

The exoatmospheric target signature code (EXOSIG), a segment of the Optical Signatures Code (OSC), is designed to calculate the optical signatures of targets (reentry vehicles, decoys, etc.) during exoatmospheric flight. EXOSIG is divided into nine distinct sections, two of which supply information to the remaining sections and not to the user of the code. These two routines (TARG and EARTH) are, therefore, presented as appendixes rather than in the main body of this volume. The remainder of the exoatmospheric code is comprised of seven primary sections, each of which is available to the user depending upon which types of targets and calculations he desires. Any number of calls may be made to any number of routines. An end-of-file test will terminate the job. The physics utilized in the development of each section's code and the input/output information necessary to or resulting from each of the calculations is different for each section and is presented. The choice of which routine (available to the user) is required by him is based upon the target configuration, its surface material properties, and whether the user desires the target's optical signature or the polarization content of its optical signature.
