Paper Abstract

This paper describes how low resolution SAR image products with a high number of looks can be simulated from calibrated amplitude SAR imagery. The simulation method reduces the resolution of the input imagery by smoothing, however the resulting product has a higher number of looks than is required, so the speckle noise has to be increased. This is achieved y using gamma distributed noise.the smoothing process is also normalized to preserve the calibration of the original imagery. Examples of simulated products and validation result for the products are also presented.
