Anthropogenic Signals Observed Using Interferometric Synthetic Aperture Radar In The Pacific Northwest

Other Titles

Abstract

Interferometric Synthetic Aperture Radar (InSAR) has developed over the past few decades as a tool with many applications to studies of crustal deformation. This thesis focuses on two signals observed in interferograms covering the Pacific Northwest. A prominent signal observed in many interferograms covering the region is associated with the logging of forests. We make use of the dependence of the topographic component of interferometric phase on the spatial separation between the sensor's locations at the two times of image acquisition to determine the height of scattering elements within vegetated regions, taken to be a proxy for canopy height. A second signal is associated with the transport of material due to the operations of the Centralia power plant and mine in Centralia, Washington. We estimate the volume and time history of material displacement for the area surrounding the power plant.
