Abstract
The present invention can be summarized by use of a diffraction limited SAR giving large integration angle and a short depth of field which gives that energy from underground targets is focused independently at different depths to enabled imaging. The radar device according to the invention should be implemented by considering the following parameters: Choice of the appropriate illumination geometry, i.e. elevation angle θ, and the appropriate use of low frequency diffraction limited SAR processing to obtainD imaging, and the choice of an appropriately low radar frequency.
