The results of COSMO-SkyMed InSAR data processing for three Russian regions by means of PHOTOMOD Radar and SARscape software packages are presented. An analysis of 3 time series of COSMO-SkyMed interferometric pairs for Amur region shows, that mean coherence is about 0,528 - 0,557 for pairs with one-day interval, it decreases by 20% for 40 days time interval. The technique of DEM generation was worked out and estimation of accuracy of final results of InSAR processing was done.
