This paper deals with the analysis and correction of artifacts on differential synthetic aperture radar (SAR) interferometry. Particularly, we concentrate on those artifacts arising from the use in interferometric processing of low accuracy acquisition geometry data. To remove these artifacts, we propose a new algorithm able to estimate the acquisition geometry parameters with high accuracy directly from the SAR data. The application of the proposed technique to the study of the subsidence phenomena in Bologna (Italy) and the surrounding area is also presented to validate the new algorithm.

Abstract

This paper deals with the analysis and correction of artifacts on differential synthetic aperture radar (SAR) interferometry. Particularly, we concentrate on those artifacts arising from the use in interferometric processing of low accuracy acquisition geometry data. To remove these artifacts, we propose a new algorithm able to estimate the acquisition geometry parameters with high accuracy directly from the SAR data. The application of the proposed technique to the study of the subsidence phenomena in Bologna (Italy) and the surrounding area is also presented to validate the new algorithm.
