Groundbased radar interferometry: Results of experimental campaigns for landslides monitoring

ABSTRACT: Results of two experimental data collections carried out in Italy by means of a ground based SAR system operating at C band, devoted to the monitoring of two landslides are reported. SAR images and related maps of phase difference variation of the observed scenario obtained from time sequences are analyzed to estimate terrain motion. The two described cam-paigns confirmed the potential of microwave interferometry but also the occurrence of decorrela-tion on interferometric maps when long time intervals separate the data acquisition.
