Diffuse scattering (DS), mostly originated at rough surfaces, can be modeled by effective roughness (ER) models. In ER models, the object surface is divided into tiles and the DS field amplitude associated with each tile is given. Assuming the phases associated with different tiles are independent, this TD investigates the spatial correlation of phases for a single tile when the receive antenna moves relative to the object surface. It is found that the spatial correlation can be modeled as the damped cosine correlation function, and the function parameters are dependent on the angle between the movement direction and the perpendicular direction to the tile surface. Different spatial resolutions of the movement and different frequencies are analyzed.
