The “atmosphere” can be broadly defined as the envelope of gases surrounding the earth. This envelope absorbs energy from the sun and weather; its radiance based on the termperature of the gases within it. Therefore an infrared signature code must have the flexibility to account for atmospheric effects that we know will affect our analysis in an extremely important way.
Including atmospheric effect is critical for any type of long range imaging or sensor modeling. MODTRAN is the definitive standard when modeling atmospheric conditions, and it is deeply embedded into our code. Because “weather happens”, users can adjust and provide control by adjusting sky dome, radiance path, and solar effects, among many other things that might effect a signature calculation. These are all enhanced with our use of MODTRAN.
As mentioned, customization is important but our job is to bring those options to you with usability in mind. We utilize the brilliance of MODTRAN and embedded it in the most user friendly and flexible computing environment we could provide.
