Overview
This raster function corrects interswath backscatter discontinuities caused by thermal noise, resulting in a more seamless synthetic aperture radar (SAR) Sentinel-1 image.
Notes
Correcting or removing thermal noise is required to normalize the backscatter signal within the entire SAR image, which is essential to both qualitative and quantitative use of SAR data.
Thermal noise is most obvious in cross-polarization SAR images, such as VH or HV, and SAR images with low backscatter.
