Abstract:

Two computer modeling programs, LOWTRAN6 and DMAD have been converted for use at the Naval Postgraduate School. LOWTRAN6, used to model the propagation of optical radiation through the atmosphere at low resolution, has been modified to permit interactive use on the schools IBM 3033AP computer two additional programs have been developed to provide interactive data acquisition and plotting. DMAD has been implemented on a VAX-11780 computer it is used to model the effectiveness of infrared countermeasure decoys against infrared-seeking anti-ship missiles. Work has also been conducted toward the conversion of FASCODE, an infinite resolution line-by-line transmittanceradiance code. The AFGL MAIN line parameters tape has been implemented on the IBM 3033AP. Many computer programs presently used in the mathematical modeling of weapons and combat systems ignore some critical physical parameters. Using LOWTRAN6 data, the importance of including atmospheric parameters such as transmittance in a model such as DMAD has been demonstrated.
