Polarization Microwave Holography: An Extension Of Scalar To Vector Holography

Whereas in the optical region commonly catan hoeognaphy is used to describe the process of wavefront reconstruction, it is shown that polarization effects can no longer be neglected in the microwave and mm-wave regions and an extension to vegan hotogitaphy is required. Based on a succint review of previous studies on considering polarization properties in holography, it is apparent that a complete vector holographic treatment has yet to be formulated. Therefore, various basic properties of the object scattering matrices and their transformation invariants are introduced together with some pertinent descriptions of coherent versus non/incoherent scatter effects from rough surfaces which then allow a complete formulation of vector holography. Finally it is shown that a further generalization of vector holography incorporating recording of magnetic (energy) intensities in addition to the electric intensity, may enable us to recover simultaneously the shape and the averaged surface impedance of a scatterer relative to some reference surface impedance.
