Um die langfristige Genese einer Landschaft nachvollziehen zu k��nnen, ist es n��tig, die Prozesse vergangener Zeiten bzw. die daraus resultierenden Gel��ndeformen m��glichst genau zu rekonstruieren. Neben der Messung aktueller Prozes

For avalanche victims a short burial time is imperative for a good chance of survival. Although airborne radar systems have been used for a long time in monitoring snow accumulation, their ability to quickly cover large areas of terrain is however no

Anti-personnel fragmentation mines and improvised explosive devices often use metallic wires-so-called tripwires-for the trigger mechanism. Depending on environment and vegetation, these wires are hardly visible. Therefore, an airborne synthetic aper

Humanitarian demining is still mainly carried out by hand. The most trusted and widely used technical tool is probably the metal detector. However, these sensors are hand-held devices which are operated closely to the surface. To make the process of

Ground penetrating radar (GPR) is one of the tools supporting mine detection. In this contribution a wide-band frequency-modulated-continuous wave (FMCW) GPR operating in the frequency band from 0.6 GHz to 4.6GHz in a bistatic configuration is presen

In this contribution two different types of broadband antennas namely a logarithmic-periodic dipole antenna (LPDA) and a transversal electromagnetic (TEM) horn antenna for ground penetrating synthetic aperture radar sensors are presented. These anten
