I think I have met another tricky problem, here is my result after run stamps(5,5):
I have 13 images(1 master and 12 slaves), I split them into 3 stack(each has 1 master and 4 slaves) and export them separately, after I merge them and process them by StaMPS, I get the result as above(the 12th ifg is the master-master ifg).
The PSs seems right, because the fringe they formed are just like ifgs. However, it is very strange that 1-4 ifgs fringe are similar, 5-8 ifgs fringe are similar, 9-12(except master-master) ifgs fringe are similar, but they are quite different from each other. And the similar ifgs belongs to same stack.
I was thinking it maybe in the interferogram formation step, I have done Substract flat-earth phase, since they belong to different stack, the result might be different.
I tried not to substract flat-earth pahse in interferogram formation, but the result is not good, fringes are too dense. Maybe put all images into one stack can solve this, but it requires very high memory.
Do anyone has an idea or meet the same problem?@katherine@ABraun
