Introduction
Thermal noise correction can be applied to Sentinel-1 Level-1 Single Look Complex (SLC) products as well as Level-1 Ground Range Detection (GRD) products which have not already been corrected. The operator can also remove this correction based on the product annotations to re-introduce the noise signal that was removed to produce the original product. Product annotations will be updated accordingly to allow for re-application of the correction.
Notes
Sentinel-1 Level-1 products provide a noise look-up table (LUT) file for each measurement data set. The values in the de-noise LUT, provided in linear power, can be used to derive calibrated noise profiles matching the calibrated GRD data. Bi-linear interpolation is used for any pixels that fall between points in the LUT.
Parameters
The only parameter for this function is the input Sentinel-1 Level-1 GRD or SLC product.
| Parameters | Description |
|---|---|
Raster | The Sentinel-1 input raster you want to process. The function will use the LUT file to either apply the thermal correction or remove the correction depending on the contents of the LUT. |
