Analysis of seasonal changes in high resolution repeat pass SAR image pairs by the CoVAmCoh method

SAR images are difficult to interpret and there is a need to support human interpreters by image analysis algorithms. The potential of the CoVAmCoh analysis is demonstrated and discussed elsewhere ([7], [8]). The CoV (Coefficient of Variation), the amplitude, and the coherence are calculated and jointly evaluated. This paper is focused on the analysis of seasonal changes by the CoVAmCoh method in 13 TSX image pairs (ascending and descending orbit) of the same location covering nearly half a year. The robustness of the method is demonstrated and discussed. The introduced interpretation rules are evaluated and refined.
