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