Please explain how this can be done in SNAP for sentinel1 SLC product.
When I'm doing the range doppler correction in SNAP the pixel spacing has been adjusted to 10m. But I am unable to under this aggregation to 100 by averaging in linear scale. This line has been taken from the paper entitled "Sentinel-1 snow depth retrieval at sub-kilometer resolution over the European Alps" from it's section 2 Data and Methodology.
