S1 Coherence

Grassland Mowing (L4B) processor

How is the change in between the coherence calculated?

  1. Calculation of the coherence within one image (phase change of the outgoing signal and backscattered signal), each for T0 and T-1 --> then comparison of the both coherences

or

  1. Comparison of the phases T0 vs. T-1 only

Thank you very much!
