Speckle Noise Reduction in SAR Images Using Double-Density Dual Tree DWT

Authors : Hadeel Nasrat Abdullah , Mohammed Fadhil Hasan and Qussay Salim Tawfeeq

Abstract: Synthetic array technology permits the achievement of very high mapping resolution in azimuth direction and is obtained by the synthesis of radar data obtained over a considerably longer aircraft flight path than the azimuth resolution cell. Synthetic Aperture Radar (SAR) images are inherently affected by multiplicative speckle noise, which is due to the coherent nature of the scattering phenomenon. This study describes a method of speckle reduction in Synthetic Aperture Radar (SAR) images based on the double density dual tree Discrete Wavelet Transform (DWT).
