Abstract

The structured infrared backgrounds created by nuclear detonations in the atmosphere are an important element of the scenes generated by the SSGM code. SSGM utilizes state-of-the science Defense Nuclear Agency (DNA) computer codes to provide nuclear disturbance caused environments. The SSGM Prototype was delivered with a data base for a single nuclear burst (10 Megatons at 120 km) in three spectral bands (SWIR, MWIR and LWIR). The data base was generated with the DNA NORSE code. The Baseline SSGM will have a more robust capability to generate Nuclear Backgrounds with the incorporation of the DNA PEM code into its run- time generation capabilities. PEM (Propagation Engagement Module) calculates propagation environments from a NORSE-generated data base. NORSE-gener- ated data bases will be included in the SSGM element library. PEM will be exercised by SSGM to create scenario specific background radiance maps and opacity maps which will be stored in the run-time library. Initially Version 3.3 of PEM will be installed in SSGM. The architecture will be flexible so that future PEM versions and database upgrades can be included straighforwardly in SSGM. The impact of bright nuclear backgrounds on sensors is highly dependent on the spatial and temporal structure exhibited by those backgrounds. The DNA produced STRCTR module, which modulates deterministic backgrounds with small scale temporally correlated spatial structure, has been incorporated into SSGM. STRCTR will be extended to support several of the phenomena modeled in SSGM. In the paper, high resolution examples of structured nuclear images will be shown. Also the range of nuclear burst scenarios that will be handled in the baseline SSGM will be indicated.
