Combining persistent scatterer interferometry (PSI) and SAR tomography approaches has the potential to overcome lay-over scenarios in urban areas and may thus increase the level of detail of differential interferometric measurements of displacements in such environments. In this paper, we report the current status and results of our efforts to integrate SAR(More)
A processor's performance and power consumption are tied; an increased performance demands more power, and vice versa. An optimal tradeoff can only be achieved by an improved prediction of the task execution times, prior to an efficient scheduling. Moreover, since the processor's soft error rate is a function of its operating voltage, it is also linked to(More)
—Persistent Scatterer Interferometry (PSI) inherently assumes a single temporally coherent scatterer inside a range-azimuth resolution cell. This restriction leads to the rejection of numerous persistent scatterer (PS) candidates, particularly in urban areas where layovers occur frequently. Moreover, in case of high-rise buildings, it is necessary to(More)
A single SAR image provides 2D reflectivity along slant range and azimuth coordinates. The reflectivity in elevation is not explicitly imaged, as the backscattered echos from multiple targets at the same range distance are superposed into the same range-azimuth resolution cell despite their different elevation coordinates. Layover distortions occur(More)
