Overview
This raster function corrects backscatter disturbances caused by thermal noise in the input synthetic aperture radar (SAR) data, resulting in a more seamless image.
Removing thermal noise is necessary to normalize the backscatter signal within the entire SAR image, which is essential to both qualitative and quantitative use of SAR data.
Notes
Thermal noise is most obvious in cross-polarization SAR images, such as VH or HV, and SAR images with low backscatter.
