Tops Differential Sar Interferometry with Terrasar-x
نویسندگان
چکیده
In this paper we investigate the possibility to exploit TOPS data to measure ground displacement movements by means of Differential SAR Interferometry (DInSAR). Several critical points (i.e. coregistration) have to be faced during the data processing since, due to the TOPS signal characteristics, the interferometric chain is very sensitive to small implementation errors. The obtained results will be compared with the ones conventionally retrieved when applying DInSAR on stripmap data. Finally, the potential of DInSAR measurements, when combining TOPS and stripmap data by means of point-like scatterers, will be also analyzed. The work presented in this study was funded under ESA-ESTEC contract number 22243/09/NL/JA.
