The widespread adoption of 3D microwave holographic imaging has been severely restricted by the inability to record results in a fast and inexpensive manner. This work will develop a novel holographic imaging technique which overcomes these difficulties and will enable high quality 3D images to be obtained from a simple measured intensity pattern. Traditional microwave holographic imaging techniques have measured amplitude and phase directly using complex equipment in a slow and costly manner. This may be contrasted with an indirect approach adopted at optical frequencies using a two-stage process, the first stage of which is the recording of a holographic interference pattern of the signals scattered by the object with a phase ;coherent offset planar reference signal. This recording can be done in a fast and inexpensive manner using simple scalar detectors. The second stage )f this process, image reconstruction, is achieved by re-illuminating the hologram with the original reference signal. The first step in the proposed research will be to synthesise the required offset reference plane wave electronically as a direct radiated reference signal is not achievable at microwave frequencies . This signal can then be combined with the signals scattered from the object to produce a measurable 2D holographic interference pattern. The second stage in this process. 3D image reconstruction. will be performed using computer software routines.
