Hello
I have a question about APS estimation. I work with 19 TerraSAR-X images in HH polarization. For APS estimation, I have been running some test with different threshold of height estimation ([-5 5],[-10 10],[-15 15], [-25 25], [-30 30],[-35 35]). The results are as shown in the attached word.
I would like to ask you how can we understand which thresholds are the appropriate ones for the analysis in the height parameters?
If sigma connections residual heights are closer to 0, they will be appropriate?
How can we understand which thresholds are the appropriate ones for the analysis in the linear trend parameters?
Best regards
