Three-Dimensional Microwave Holographic Imaging Employing Forward-Scattered Waves Only

Abstract EN

We propose a three-dimensional microwave holographic imaging method based on the forward-scattered waves only.

In the proposed method, one transmitter and multiple receivers perform together a two-dimensional scan on two planar apertures on opposite sides of the inspected domain.

The ability to achieve three-dimensional imaging without back-scattered waves enables the imaging of high-loss objects, for example, tissues, where the back-scattered waves may not be available due to low signal-to-noise ratio or nonreciprocal measurement setup.

The simulation and experimental results demonstrate the satisfactory performance of the proposed method in providing three-dimensional images.

Resolution limits are derived and confirmed with simulation examples.
