All Altitude Atmospheric RT Algorithm for Scene Generation

MDA has an urgent need for rapid and accurate scene generation codes. The current highly accurate state-of-the-art (SAMM2) is limited in two ways: (1) it is designed to compute a single line-of-sight as opposed to scenes and (2) its core numerical algorithm is geared toward reproducing the exact line-by-line result as opposed to being optimized for speed. This Phase II intends to address both technical limitations. To address scene generation requirements, SAMM2 will be upgraded to efficiently compute collections of related lines-of-sight. These upgrades will constitute additional functionality. No existing capabilities will be eliminated. To address rapid computation requirements, SAMM2 will gain a collection of new radiation transport algorithms. These algorithms will be constructed either in-house or by third-party developers and will integrate into SAMM2 through a software interface. Within SAMM2, the algorithms will operate at varying degrees of speed and fidelity. Collectively, these algorithms will allow MDA to select the mix of speed and fidelity appropriate for any given problem with all algorithms operating within a single, physically consistent background code.
