Target and Scene Simulation:
Spectral Sciences has developed or supported a number of US Government and other computer codes for calculating and displaying target images and spectral signatures at wavelengths ranging from the visible through the thermal infrared. Examples include SPIRITS, QUID, and GUIDES, MCScene and kURT.
- SPIRITS - SSI provides support for the Joint Army Navy NASA Air Force (JANNAF) SPIRITS aircraft image model.
- QUID (QUick Image Display) - An SSI-developed code that computes and displays radiance images at animation rates. Runs on graphics workstations supporting the OpenGL 3-D graphics-rendering interface.
- GUIDES is a Windows-based environment that lets you run SPIRITS on your personal computer. GUIDES saves time and money by providing quick setup, automatic error checking, and graphical and image display and analysis tools all in one integrated package. For more information about GUIDES, please contact us at guides(at)spectral.com.
- MCScene is a Monte Carlo code for simulating radiometrically accurate spectral imagery including 3-D backgrounds, atmospheric descriptions, and embedded objects.
- kURT (k-distribution based Ultra-fast Radiative Transfer), a package of transmittance and radiance routines designed for highly efficient scene simulation. kURT leverages a pre-calculated MODTRAN-based correlated-k database to achieve several orders of magnitude improvement in computation speed compared to MODTRAN for broad optical bandpasses and multiple lines of sight.
