Abstract:
The use of indirect holographic techniques for antenna testing has been shown to offer a simple, low cost scalar technique for the reconstruction of complex antenna aperture fields. This work extends the use of indirect holography to the imaging of objects. This work provides a brief outline of the basic theory of indirect microwave holography and how it can be used for the reconstruction of scattered complex fields at the measurement plane and how these results can be back propagated to provide images of the scattered fields at the position of the original object. The techniques described have been validated by experimental results on a range of objects including buried objects. © 2013 IEEE.
