Generate Sentinel-1 coherence time-series

[ABraun]

for Sentinel-1, any multiple of 6 is valid, as long as the same track/relative orbit is used. But the longer the period between the image, the lower is the coherence.

thank you, @heinzollerketchup. Generally, the longer the temporal baseline (=the time between two images) the higher is the decorrelation which leads to small coherence values. It also depends on the cover of the analyzed surface. Bare ground mostly shows slower decorrelation than one with high vegetation cover. As you can see here (tested with S1 data), coherence decreases from 0.7 to nearly 0.1 within 6 12-day-cycles (12, 24, 36, 48, 60 and 72 days, blue to red) [image] Source: http://ieee…
