Pixels and resolution

i am using snap and the data of Sentinel 1A , tell me how i can do more resolution for a building by using radar interferometry , we know all the resolution of sentinel 1A is 5 m

best regard

5 meter is only the resolution of StripMap products which are available for a few selected sites, mostly of volcanic activity.

The actual spatial resolution of IW products (95% of the data archive) is 20 meters, resampled to 10 meters of pixels spacing: https://sentinel.esa.int/web/sentinel/user-guides/sentinel-1-sar/resolutions/level-1-ground-range-detected

you don’t you give me the answer
but there is a development for resample the pixel to 1 m as an example

You can, technically, resample to any pixel size you want but that does not increase the detail provided by the image.
