By means of tomograhic radar technique consisting of a coherent combination of
large numbers of synthetic aperture radar images acquired by several air or space
SAR systems having different look angles, a real three-dimensional imaging of volume
scatterers is achieved. This allows the separation of the backscattered signal
of volume scatterers in the height direction which can be further evaluated independently.
The invention can be put to use in the three-dimensional analysis of vegetation
layers and ground strata, but also for imaging and mapping of buildings, urban
areas and mountainous terrain.
