Interferometria SAR Differenziale per il Rilevamento delle Deformazioni

The differential interferometric SAR technique represents a powerful remote sensing tool for the monitoring of terrain deformations. The paper concisely describes the properties of the differential interferometric phase, which represents the main observation for the estimation of the deformations. Then the paper discusses the main features of a new interferometric SAR procedure which applies an integrated approach for the treatment of DInSAR observations. In particular, the interferometric SAR processing and the least squares adjustment procedure to estimate the terrain deformations velocity are described. Finally an application of the proposed procedure is illustrated over simulated data.
