Abstract

Nonspecular scattering from the facades of large buildings is dominated by windows and decorative masonry. The placement of these features is nearly periodic. As a result, scattering from these buildings takes the form of diffraction orders, rather than diffuse scattering from a randomly rough surface. Computing the scattering for many realizations of building facades allows us to average the scattering properties to achieve a single smoothed scattering coefficient that can be used to represent all of the buildings.
