Scientific paper

CBSD Version 2 addresses the development of algorithms and software which implement realistic models of all the primary celestial background phenomenologies, including solar system, galactic, and extra-galactic features. During 1990, the CBSD program developed and refined IR scene generation models for the zodiacal emission, thermal emission from asteroids and planets, and the galactic point source background. Chapters in this report are devoted to each of those areas. Ongoing extensions to the point source module for extended source descriptions of nebulae and HII regions are briefly discussed. Treatment of small galaxies will also be a natural extension of the current CBSD point source module. Although no CBSD module yet exists for inter-stellar IR cirrus, MRC has been working closely with the Royal Aerospace Establishment in England to achieve a data-base understanding of cirrus fractal characteristics. The CBSD modules discussed in Chapters 2, 3, and 4 are all now operational and have been employed to generate a significant variety of scenes. CBSD scene generation capability has been well accepted by both the IR astronomy community and the DoD user community and directly supports the SDIO SSGM program.
