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.
Hello. The region I’m trying to generate the displacement image is between two IW. So, now I want to do something like merge or anything else to process.
I tried S-1 TOPS Merge after S-1 TOPS split and then S-1 TOPS deburst.
But I won’t be able to do the back-geocoding and the rest.
What should I do?
Follow the tutorial(s) that teach you to generate S-1 interferograms. You will only see the displacement well if the ground-movement is substantial compared with the atmospheric artefacts, which are always present.
I don’t think that is displacement but simply atmosphere that has been highlighted by the weird colourmap. There’s a huge perceptual difference in a tiny change from about 0.041 to 0.044. You should switch to a colourmap with uniform or linearly changing brightness, for example from the cubehelix family of colourmaps.
