Abstract

We describe our approach for the modeling of space objects on the basis of 3-D designs supplemented with surface material assignments and their associated electro-optical properties. Challenges with this approach include incorporating Bi-directional Reflectance Distribution Function (BRDF) models that are both representative and robust over a range of wavelengths. In view of the small angles subtended by most space objects observed at a distance, any limitations of the applicability of BRDFs measured with much larger laboratory fields of view need to be assessed. In addition, any observational effects associated with partial coherence under conditions addressed by the van Cittert-Zernike theorem require investigation. More comparisons of predictions and observations are needed to guide these developments.
