Object inspection is a field of increasing interest for many situations like modification of dry walls done by craftsmen. The main interest here is to locate infrastructural objects inside dry walls where the modification should be made so as to avoid accidents. This paper presents a 3D SAR imaging method for the visualization of the hidden objects including an investigation of polarizational effects for dry wall inspection. The imaging modality behind this approach will be explained in geometry, signal theory, and the used experimental setup. Selected results from a real dry wall setup are shown and explained in detail.
