Abstract:
An efficiency of natural permanent scatterers like as power lines towers and engineering constructions in urban territories as reference targets in interferometric observations of snow covers dynamics on PALSAR-2 images Selenga river δ in Buryatia is studied. The discrepancy between signals of snow-free reference targets and surrounding fields occurs in the case of snowfall between the subsequent SAR observations constituting interferometric pair. From the processing of 3 adjacent PALSAR-2 interferometric pairs the snow layer increment up to 26 cm was detected, what is in a good agreement with measurements of local meteorological station.
