Hello! I am very fresh in the SAR analysis, so excuse me if I am making silly mistakes.
I try to make polarimetric decomposition from Sentinel-1 SLC.
Firstly, I did calibration. Later, S-1 TOPS deburst and from this point I have an issue. The output is smaller than input and when I try to do polarimetric decomposition there is error that I need input to be a full polarimetric product.
I have tried this type of decomposition and indeed it works. Only issue now is that the scene is smaller than original one and it is due to deburst - I do not know how to make decomposition of whole scene.
First you split, calibrate (complex) and deburst your S1 product, optionally you apply speckle filtering.
Then you select Radar > Polarimetric Classification > Unsupervised Polarimetric classification
In the dropdown menu you select H Alpha Wishart Dual Pol
