Abstract : Research in high resolution microwave imaging has to date concentrated 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 targetr derived reference technique to produce images of the scattering centers on complex-shaped bodies with unprecedented resolution and quality 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 or remote objects specially through the earth's atmosphere is desired.
