Resumen:
Physical changes that occur in land surfaces between two SAR acquisitions affect the precision of repeatpass synthetic aperture radar differential interferometry (DInSAR). This phenomena is defined by the temporal term of interferometric coherence value in each interferometric pair. In this work we carried out an empirical study of the COSMO SkyMed (X-band) temporal decorrelation in both polarization modes, HH and VV. We analysed the polarization effect on the temporal coherence in relation with: 1) percentage of coherent pixels in the regions of interest (ROI), and 2) the seasonal behaviour over the vegetated areas.
