SPECTRUM: a wide SPECTrum Radiative transfer Unified Model and algorithm development system

Orbital Micro Systems (OMS) proposes to build SPECTral Radiative transfer Unified Model (SPECTRUM), a pan-spectral radiative transfer and algorithm development system.Ā SPECTRUM fulfills a need by the Navy for a unified Radiative Transfer Model (RTM) framework from UV to radio frequencies to aid in instrument design and algorithm development.Ā SPECTRUM will integrate existing RTM and retrieval algorithms to collectively span the desired range of frequencies.Ā The Phase I objectives are 1) Design the SPECTRUM architecture to run multiple RTMs and algorithms.Ā Build a rapid prototype with two RTMs. 2) Design a Spectra database of radiative spectra and other inputs required to run various RTM and algorithms.Ā Use case to demonstrate how to use the database by changing the input spectra for one RTM to increase its frequency range. 3) Design an algorithm testbed to support the development of retrieval algorithms.Ā Build a rapid prototype Testbed.Ā Apply the testbed to two use cases: porting an algorithm and designing a new algorithm. OMS will write a report describing the SPECTRUM architecture and three Use Cases.Ā OMS will produce a full Phase II development plan, a SPECTRUM prototype with two integrated RTM, a database design, and a prototype testbed.
