A New Method of the Speckle Reduction to SAR Based on Sparse Decomposition
PO Box · He'nan kexue · 2011
The study of the speckle is a hotspot to Synthetic Aperture Radar(SAR),the traditional way to reduce the speckle is either difficult to protect image edge characteristics or reduced the resolving power,in this paper a new signal processing method Sparse Component Analysis(SCA)is introduced,and applied to reduce the speckle to SAR,the result to the emulator show it is an effective approach to restrain the speckle to SAR.
