The development of indirect microwave holography for measurement and imaging applications

This work describes the development of indirect holographic techniques for microwave measurements and imaging. It outlines the basic theory of indirect holography and how it relates to optical holographic techniques. It starts with a description of the initial work using a single receiving antenna for the determination of antenna radiation patterns and the reconstruction of antenna aperture fields. This is followed by a description of how these techniques can be adapted for the imaging of passive objects. It also outlines the techniques for the imaging of objects using indirect holography. These techniques include simple back propagation for the reconstruction of objects in free space and inverse scattering techniques for objects in inhomogeneous media.
