Teng publishes two papers

​Two papers were recently published based on the work of Teng Wang, a Postdoctoral fellow in the CDI group.  The title of the first study is "Phase-ramp reduction in interseismic interferograms from pixel-offsets". This study shows that InSAR phase ramps are in part caused by satellite timing-parameter errors and Teng proposes a method to estimate these errors and thus improve interseismic observations. This study was published in IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing. The second paper is entitled "Improved SAR image coregistration using pixel-offset series" and presents a method that leads to better coregistration of SAR images, improving InSAR coherence and observations. This paper appeared in IEEE Geoscience and Remote Sensing Letters.
