This contribution deals with guided radar level measurements of liquid materials in large metal tubes, socalled stilling wells, bypass or still pipes. In the RF domain these tubes function as overmoded circular waveguides ...

Freshwater lenses, as important resource for drinking water, are sensitive to climate changes and sea level rise. To simulate this impact on the groundwater systems, hydraulic subsurface models have to be designed. Geophysical ...

SAR Interferometry (InSAR) is a technique to derive Digital Elevation Model (DEM) from at least two complex SAR images. The data are either taken simultaneously (single-pass mode) or sequentially (repeat-pass mode) by ...
