when I use MST method processing ASAR data，I already process interferograms processing and coherence map generation 。I use Amp. Stab. Ind plus Sp. Coher method to choose PS points， the software has a message is
files D:\SY\ASAR\08yihou\1\RESULTS\ASICoher and D:\SY\ASAR\08yihou\1\RESULTS\ASICoher.mat not found
0 points with Amp. Stab. Ind plus Sp. Coher. > 0.70 , in window from 1 to 380 samples, from 1 to 2240 lines
ignoring birth and death dates, selecting all targets
the message u posted states that the “Amp. Stab. Ind plus Sp. Coher.” parameter is not found.
Such parameter is generated when you save the Spatial Coherence.
So, my suggestion is: run the coherence map generation again. I expect that in this way you will solve the problem.
If on the contrary the “Amp. Stab. Ind plus Sp. Coher.” will still be missing, I expect that you will get an error message during the coherence map generation. In such case, send us laterror.mat and log files (make sure the log contains the last messages)
ok, now I understand the issue.
in fact, we did not consider this situation, we will modify the code for that.
The fact is that you are multilooking. as a consequence, the “Amp. Stab. Ind plus Sp. Coher.” is useless.
in fact, the amplitude stability index is a full-resolution index. if you multi-look, it makes no sense using it…
