A Comparison of BRDF Representations and their Effect on Signatures

Abstract

The application of advanced low observable treatments to ground vehicles has led to a requirement for a better understanding of effects of light scattering from surfaces. Measurements of the Bidirectional Reflectance Distribution Function (BRDF) fully describe the angular scattering properties of materials, and these may be used in signature simulations to accurately characterize the optical effects of surface treatments on targets. This paper examines some of the popular parameterized BRDF representations and shows their effect on signature calculations.
