Remove Thermal Noise (Image Analyst)

ArcGIS Pro 3.4 | | Help archive

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.

  • This tool does not support a geodatabase as an output location.
