Abstract :
The authors examine radar speckle from a non-traditional perspective. Instead of viewing radar speckle as noise, they attempt to assess the information content of radar speckle. A speckle identification algorithm is developed to separate speckle from pixels of “normal” returns. The relationships between land cover types and the density and roughness of speckle are examined
