Combine two S-1 SLC IW products without geometric?

My research area is covering in two S-1 SLC products.

I wanna combine two S-1 SLC IW products without geometric method because I hope they can keep “sar” products. If they become geometric images(ex: sat-mosaic) that I can’t continue to analyze(ex: interferometric, unwrap…)

I hope to combine this two S-1 SLC IW products into one product. I split IW3 two bursts(up) and another IW3 two bursts(down). Take a look at the picture below.

Please experts on this platform give me some advises or answers to solve the question!!!
THANK A LOT!!!

you mean you want to keep your data in radar geometry (slant range) instead of converting it to ground range geometry?

You can try the Sentinel-1 Slice Assembly Tool

THANK YOU!!
I try this method right now!!

Thank you for helping me!! This method is useful~~

Dear ABraun ,
I wanna combine IW1 and IW2 interferograms. But using Sentinel-1 Slice Assembly tool I’m not getting. Please tell me the steps.

Thanks.
