SAR speckle noise reduction using Wiener filter
Tae H. Joo, Daniel N. Held · NASA Technical Reports Server (NASA) · 1983
Synthetic aperture radar (SAR) images are degraded by speckle. A multiplicative speckle noise model for SAR images is presented. Using this model, a Wiener filter is derived by minimizing the mean-squared error using the known speckle statistics. Implementation of the Wiener filter is discussed and experimental results are presented. Finally, possible improvements to this method are explored.
