Abstract:
This paper will discuss the use of the Monte Carlo Scene (MCScene) code to simulate low light situations where the sun is near or below the horizon. MCScene is a high-fidelity model for full optical spectrum simulation. It provides an accurate, robust, and efficient means to generate spectral scenes for algorithm development and sensor trade studies. MCScene utilizes a Direct Simulation Monte Carlo (DSMC) approach for modeling 3D atmospheric radiative transfer including full treatment of molecular absorption and Rayleigh scattering, aerosol absorption and scattering, and multiple scattering. This paper will examine rare target detection statistics in simulated scenes as the sun moves from overhead to sunset and eventually to twilight.
