Database-Driven Discrete Debris Signature Model (4DSM)

In this effort, Spectral Sciences, Inc. and subcontractors Corvid Technologies, Inc., Sierra Engineering and Software and MTSI propose to develop the Intercept Discrete Debris Signature Model for Solid Rocket Motors (ID2SM-SRM) toolkit to better predict the time-dependent EO/IR and radar signature for solid-rocket motor (SRM) fuel debris, or chuff. The ID2SM-SRM toolkit will consist of two parts a database of emissivities and radar cross sections measured for SRM debris pieces collected from static test fires and the development of new debris generation tools that will harness this database to better predict the types of debris that is created in the SRM cavity after blow-down. The ID2SM-SRM database will be immediately available to both MDA SRM chuff debris codes such as ChuffSig and STEM and to radar and optical scene generation tools such as TAD-64, REVEAL, BLAST3 and OPTISIG. This effort will leverage previous work by Spectral Sciences, Inc. (SSI) and its collaborators, Sierra Engineering & Software, Inc. (Sierra), Corvid Technologies (Corvid) and Modern Technology Solutions, Inc. (MTSI) on the development of predictive tools for modeling fuel debris radar and EO/IR signatures. Phase III will see the development of additional tools and continued population of the database.
