Paper Abstract

In the LWIR, often one assumes a scene does not contain solar reflection. To test this assumption, a simple scene model is analyzed for two BRDFs: Lambertian and measured data. For certain geometries, non-negligible solar reflection is observed at 8, 10, and 12 microns when using the BRDF data. Additionally, the wavelength variation of the pupil plane radiance data differs from the Lambertian case when using a BRDF, not just the magnitude. These results suggest that even in the LWIR, BRDFs should be incorporated to account for solar radiance effects.
