This paper introduces a newly developed interferometric coherence model that can be used to preselect pairs of images for InSAR time-series processing. As coherence values are pre-calculated, automatic image selection can be performed at very little computational cost and computing resources can be dedicated to the few remaining selected interferograms. This can lead to significant throughput improvements...
Remote sensing plays a critical role in operational volcano monitoring due to the often remote locations of volcanic systems and the large spatial extent of potential eruption pre-cursor signals. Despite the all-weather capabilities of radar remote sensing and its high performance in monitoring of change, the contribution of radar data to operational monitoring activities has been limited in the past...
When a Synthetic Aperture Radar (SAR) signal propagates through the atmosphere on its path to and from the sensor, it is inevitably affected by atmospheric effects. In particular, the applicability and accuracy of Interferometric SAR (InSAR) techniques for volcano monitoring is limited by atmospheric path delays. Therefore, atmospheric correction of interferograms is required to improve the performance...
