Mapping ice-shelf flow with interferometric synthetic aperture radar stacking
Interferometric synthetic aperture radar (InSAR) observations of ice-shelf flow contain ocean-tide and atmospheric-pressure signals. A model-based correction can be applied, but this method is limited by its dependency upon model accuracy, which in remote regions can be uncertain. Here we describe a method to determine two-dimensional ice-shelf flow vectors independently of model predictions of...
متن کاملInterferometric Synthetic Aperture Radar
This paper provides a brief review of interferometric synthetic aperture radar (InSAR), its history, the theory, and design / implementation / processing issues. Along-track, single-pass and repeat-pass cross-track interferometry are reviewed. Specific topics addressed include error sources and phase-unwrapping techniques. Several examples of InSAR applications are presented. Introduction For y...
متن کاملInterferometric synthetic-aperture radar (InSAR)
Geodesists are, for the most part, a patient and hardworking lot. A day spent hiking to a distant peak, hours spent waiting for clouds to clear a lineof-sight between observation points, weeks spent moving methodically along a level line – such is the normal pulse of the geodetic profession. The fruits of such labors are all the more precious because they are so scarce. A good day spent with an...
متن کاملCoherent interferometric imaging for synthetic aperture radar
This paper shows that the coherent interferometric imaging strategy originally proposed in the context of passive or active arrays of antennas can be implemented for synthetic aperture radar, in which a single antenna is used as an emitter and as a receiver at successive positions along a trajectory. The idea is to backpropagate the cross correlations of the recorded signals over selected frequ...
متن کاملAntarctic Ice Shelf Tide Modeling Using PALSAR Interferometry
The knowledge of ocean tides underneath permanently or seasonally sea ice covered ocean and ice shelves over Antarctica, is largely unknown. Significant amount of West Antarctic ice sheet melt is through the mechanism of basal melting and due to turbulent tidal mixing. Knowledge of the ice shelf grounding lines and their extent, are critical to accurately quantify ice sheet mass balance, and oc...
