Abstract

Speckle appearing in synthetic aperture radar (SAR) images is generated by coherent interference of radar echoes from target scatters. Basically speckle noise has the nature of a multiplicative noise. In this paper procedures for defining and verifying a statistical noise model are developed and two multiplicative noise smoothing algorithms are presented. These two algorithms are computationally efficient, and have the potential of achieving real or near real-time processing. Several SEASAT SAR and SIR-B images are used for illustration.
