does anyone have any idea what can I do as as image processing to study the coherence and what parameters are involved? for example, I am working on Sentinel 1 data and I want to know how can I choose an image pair that results in good coherence estimation for further studying the movements of the landslide.
thanks in advance.
Please check these tutorials on how to calculate coherence
Landslides are non-coherent processes, coherence is always decreasing when there is surface movement. Based on coherence of different pairs you can only determine when the movement occurs.
