The use of mathematical morphology for accurate detection and identification of microwave images in the K-space domain

Abstract

The use of holography in imaging is generally confined to the optical regime. Recent advances in microwave techniques have allowed the use of multi-frequency and multi-geometry to collect phase information that can be used to construct two and three dimensional information sets. The use of longer wavelengths allows flexible configurations and applications that can penetrate propagation media and in some cases the target of interest. Microwave radiation has not been used extensively in imaging three dimensional structure using holographic approaches. The use of tomographic processing requires that data be collected at sufficient resolution to allow unambiguous slices to be constructed. This differs from interferometric techniques where there is some ambiguity (phase) that must be handled to properly reconstruct the final three dimensional image.
