Modeling the SAR response of pine forest in Southern Finland

Ground data, biologically accurate model trees, an optical mosaic, a ground digital elevation model, and a top surface model for a forested site at Tuusula, Southern Finland have been used to construct a natural model forest. Model calculations include the SAR imaging process and predict SAR image structure. CARABAS low frequency SAR images of the forested site are compared with SAR image calculations, and fractional Brownian motion based texture images. Simulated intensities and textures agree well with observation.
