Can someone explain these parameters in detail ?
I think you can find some details here.
http://sentinel1.s3.amazonaws.com/docs/S1TBX%20Offset%20Tracking%20Tutorial.pdf
there no details about these parameters in that tutorial, i read it before. what i need to learn is what these parameters stand for and what should be best for landslide measurement
did you see the corresponding help section?
Regarding the window sizes, you can also refer to the coregistration and cross-correlation.
thanks a lot Abraun. i did see the help for those parameter but had not checked the correlation ones. it helped
