This paper will discuss recent improvements made to the Monte Carlo Scene (MCScene) code to enable limb-viewing scenarios and situations where the sun is below the horizon. MCScene is a high-fidelity model for full optical spectrum (UV through LWIR) hyperspectral image (HSI) simulation. MCScene generates HSI scenes for algorithm validation, utilizing a Direct Simulation Monte Carlo (DSMC) approach...
Ground relief is a key parameter affects the open forest bidirectional reflectance factor (BRF) estimation result of a Monte Carlo ray-tracing model. In this proceeding, we propose a 3-D ray-tracing simulator for estimating the BRF for a forest with complex terrain relief. Unlike existing models, this model takes into account rugged terrain conditions by using a local normal retrieving approach based...
