ARTIFICIAL SCATTERERS FOR S.A.R. INTERFEROMETRY

摘要

The evaluation of land displacement using SAR interferometry becomes often very difficult if we consider areas characterized by limited coherence. In this cases it is necessary the use of artificial scatterers. Presently, it is possible to utilize different kinds of reflectors: mirrors, dihedrals, and trihedrals, I.e. corner reflectors. We try to develop new generations of artificial scatterers with better properties. The possibility to use the same reflector for ascending and descending orbits would be a very powerful instrument to better characterize landslides, subsidence or other displacements. Exploiting the experience achieved with Corner Reflectors a new object is proposed to pursue this objective.
