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

Please take a look at this threads about corre. Asc. and Desc.

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
