Kurzfassung
This paper presents results on SAR interferometry for data acquired in the so-called TOPS imaging mode. The rationale to retrieve accurate interferometric products with such a mode is expounded, emphasizing the critical step of coregistration. Due to the particularities of the TOPS mode, a high Doppler centroid is present at burst edges, demanding a very high azimuth coregistration performance. A coregistration accuracy of around one tenth of a pixel, as it is usually recommended for stripmap interferometric data, could result in large undesired azimuth phase ramps in each TOPS burst. This paper presents two approaches based on the spectral diversity technique to precisely estimate this coregistration offset with the required accuracy and evaluates their performance. Repeat-pass TOPS data acquired experimentally by TerraSAR-X are shown to validate the proposed approaches.
