"We define the Bidirectional Reflectivity Distribution Function (BRDF) in terms of Wigner functions so as to make its radiometric aspect compatible with the wave aspect of coherent propagation through atmospheric turbulence. We then adapt this definition in order to make it compatible with the DRDC turbulent imaging simulator for active imaging on weakly specular surfaces. This is done by defining a coherence length associated with the surface which expresses how specular it is. We demonstrate our model on a few targets and comment on its range of applicability"--Abstract, p. 1. Imaging simulation Defence R&D Canada. Valcartier Research Centre.
