Research in Image Understanding as Applied to 3-D Tomographic Imaging with Near Optical Resolution

摘要

Our research in high resolution microwave imaging has to date focused broadly on the study and development of efficient and cost-effective data acquisition and image reconstruction methods for use in lambda and polarization diversity 3-D tomographic imaging. The techniques developed, combine angular, spectral, and polarization diversity measurements with a unique target derived reference (TDR) technique to produce images of the scattering centers on complex-shaped bodies with unprecedented resolution and quality, as reported here, that exceed by far anything reported to this date. Analytical studies of information content, speckle suppression, and resolution show however that image quality can further be enhanced and made to approach and even exceed the resolution of optical systems when the imaging of remote objects specially through the earth's atmosphere is desired.
