Title: Speckle analysis and smoothing of synthetic aperture radar images
Abstract: Coherent processing of synthetic aperture radar (SAR) data makes images susceptible to speckles. Basically, the speckles are signal-dependent and, therefore, act like multiplicative noise. This paper develops a statistical technique to define a noise model, and then successfully applies a local statistics noise filtering algorithm to a set of actual SEASAT SAR images. The smoothed images permit observers to resolve fine detail with an enhanced edge effect. Several SEASAT SAR images are used for demonstration.
