Remove Thermal Noise (Image Analyst)

This ArcGIS 3.0 documentation has been archived and is no longer updated. Content and links may be outdated. See the latest documentation.

Available with Image Analyst license.

Summary

Corrects backscatter disturbances caused by thermal noise in the input synthetic aperture radar (SAR) data, resulting in a more seamless image.

Usage

  • Correcting, or removing, thermal noise is required to normalize the backscatter signal within the entire image, which is essential to both qualitative and quantitative use of SAR data.

  • Thermal noise is most obvious in cross-polarization SAR data, such as VH or HV, and SAR data with low backscatter.

  • When using Sentinel-1 SAR data, the tool corrects for interswath backscatter discontinuities, which are caused by thermal noise.
