Coregistrate ascending and descending data?

Hi all,
is it possible to coregistrate ascending and descending Sentinel-1A tops SLC IW VV data in a simple way, in order to to reduce the geographic migration of the same area in both ascending and descending data?Maybe I can study the registration between ascending and descending data.Is this feasible?

Who can give me some advice or other more convenient way?

many thanks
Lihoon

Basically it is not possible coregister them.

Then, depending your scope you may try stacking/collocation based on geocoordinates once you have both products geocoded, but not possible for applications such as interferometry…

thanks for your article
