Software: Target and Scene Simulation

Spectral Sciences has developed or supported many 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.

  • QUID (QUick Image Display) is an SSI-developed code that computes and displays radiance images at animation rates. It runs on graphics workstations supporting the OpenGL 3-D graphics-rendering interface.
  • MCScene is an SSI-developed Monte Carlo code for simulating radiometrically accurate spectral imagery, including 3-D surfaces with embedded objects, and atmospheric descriptions including cloud fields.
  • SPIRITS - SSI provides support for the Joint Army-Navy-NASA-Air Force (JANNAF) SPIRITS aircraft image model, available from the Chemical Propulsion Information Analysis Center (CPIAC).
