| Abstract | Speckle filtering of nonstationary scenes is studied in the context of estimation theory. It is shown that the problem can be solved separately for stationary in increments scenes, and scenes which are
not locally stationary. The speckle multiplicative noise model, the Kuan's nonstationary mean nonstationary variance (NMNV) scene model, and the speckle-scene product model are analysed, and their use for an accurate reconstruction of the underlying
scene signal is discussed. A protocol is introduced for speckle filtering of stationary and non stationary scenes. It is shown that the use of multi-resolution algorithms is crucial for a safe reconstruction of the underlying nonstationary radar
cross section of the illuminated scene. |
