Cryosphere plays a crucial role in regulating local and global climate. Glaciers form an important component of this frozen part of the Earth's system. They exist over a prolonged period and are largest reservoir of freshwater on Earth. The meltwater from the glaciers during warmer seasons contribute to the river systems in absence of other sources. The run-off is also useful for agriculture, power...
In principle, we can construct highly precise digital elevation model (DEM) with interferometric synthetic aperture radar (InSAR) observations. However, in actual observed images, we find so many rotaional points, namely, phase singular points (SPs), that we cannot determine the height accurately. It is significantly important to investigate the SP phenomenon. Presently the origin of the SPs is not...
This paper presents a method for removing spikes in digital elevation models (DEMs) caused by residues in interferometric synthetic aperture radar (InSAR) phase image. We consider that the scattering mechanism is properly modeled by the small perturbation method for fractal surfaces and present a model that relates the phase and magnitude in InSAR image. This data model provides the regularization...
