Sentinel 1 image looks like a bunch of black and white colors

I dont understand why this image looks like a noise, cant understand and decode objects. Any suggestions?

radar data does not capture colors but the intensity of the backscattered signal. The noise is caused by speckle and the geometry is caused by the side-looking geometry of the sensor.

Radar data is quite different from optical data, please get familiar with the basic principles.


The interferogram looks like this. I dont understand what is wrong with this

I suggest you look at some tutorials about interferometry. Here are some tutorials to get you started:

I would suggest that you start studying SAR imaging and post-processing of SAR imagery with intensity imeged (like S-1 GRD) first, before moving into InSAR.
