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 sensi-tive to small implementation errors. The obtained results will be compared with the ones conventionally re-trieved when applying DInSAR on stripmap data. Finally, the potential of DInSAR measurements, when com-bining TOPS and Stripmap data by means of point-like scatterers, will be also analyzed.
