Determination of elongation of electrically small objects in building structures by polarimetric synthetic aperture radar

Résumé

Short range synthetic aperture radar (SAR) was used to study electrically small objects. A metallic rod and a metallic sphere could not be separated in the SAR images. Polarimetric SAR images were analyzed and images corresponding to different antenna orientations were obtained by applying rotation matrices to radar data. The target intensity varied with the rotation angle. Elongation and orientation of the objects could be determined from the ratio of minimum and maximum intensity. Upper and lower limits for measurable elongation depend on measurement errors.
