SAR image simulation is important for a number of tasks in the design of SAR dedicated systems. We propose here a SAR texture simulation tool. Based on a statistical description of the local reflectivity and elevation of a surface, this tool generates seamless texture mapping patterns. The associated SAR texture renderer can provide several levels of realism, from flat 2-D texture mapping to 3-D unperfectly conducting surfaces back-scattering model, going through normal dithered Lambert law. The back-scattering model simulates polarizing, overlaying and shadowing effects, but not the multiple reflections. Using the range-buffer technique, the synthetic texture patterns are mapped on 3-D objects.
