SigSim Materials

Common, Material/Property-Encoded Synthetic Environment
 
In addition to a common atmospheric data-model, SigSimRT employs a common terrain and object data-model with the innovative Material Systems Concept (supported in a SEDRIS EDCS). Material systems allow the assignment of material configurations from a comprehensive library, and associated boundary conditions to texels, vertices and/or facets in the database. In this manner, fast SigSimRT algorithms retrieve the intrinsic physical properties and conditions such as density, thermal conductivity, specific heat, BRDF, RCS, scatter-center tables, wind speed, engine-state, etc. to synthesize the correct passband signature for EO, IR or RF sensors.
