Basic Research in Three-Dimensional Imaging from Transient Radar Scattering Signatures

摘要

The transient radar scattering signatures of a set of cone-like objects were studied, and techniques for creation of images using these signatures were investigated. The signatures were obtained from model measurements on two coherent 10:1 bandwidth complex scattering cross-section measurement systems. Ramp response signatures were generated from the measured data, and their relationship to target geometrical characteristics were analyzed. Two techniques for imaging from the signatures gathered at near nose-on look angles were investigated: Limiting Surface Imaging and Physical Optics Inverse Diffraction. Useful images, with some loss of detail, were produced. (Author)
