Sample decoded L0 data

All the documentation necessary to decode Sentinel-1 Level-0 products is providing in a single package. In addition to the documentation, it provides a sample of Level-0 product with the associated RAW decoded data in order to support the users.

Radiometric Re-compensation of Sentinel-1 SLC data

 

Changes of applied processing parameters during SAR data processing may impact the SAR data quality and can be a disturbing factor for long-term monitoring of radiometric features. Therefore, a re-compensation method has been proposed and verified which accounts for radiometric changes in particular due to different applied antenna patterns and processing gains. This method is published in an article called: Radiometric Re-Compensation of Sentinel-1 SAR Data Products for Artificial Biases due to Antenna Pattern Changes

In order to help Sentinel-1 users to implement this method in their own software tools, two dedicated examples are presented in the publication containing intermediate results. For these examples two kind of SLC SAR data products are used:

  1. nominally produced products available at official data hub (https://dataspace.copernicus.eu/) 
  2. additional products re-processed with specific input data. These specific processed SAR products can be downloaded from the SAR MPC download area: case of 2017/07/11, and case of 2019/08/03.

The required ADF are available either:

Notice however that this re-compensation cannot be applied for products processed before IPF 002.71 due to major change of the processor introducing the TOPS normalisation. The period of usage of the different version of the processor is available on this web site in the "Processor Versions" section.
