We propose a three-dimensional microwave holographic imaging method based on the forward-scattered waves only. In the\r\nproposed method, one transmitter and multiple receivers perform together a two-dimensional scan on two planar apertures on\r\nopposite sides of the inspected domain. The ability to achieve three-dimensional imaging without back-scattered waves enables the\r\nimaging of high-loss objects, for example, tissues, where the back-scattered waves may not be available due to low signal-to-noise\r\nratio or nonreciprocalmeasurement setup.The simulation and experimental results demonstrate the satisfactory performance of the\r\nproposed method in providing three-dimensional images. Resolution limits are derived and confirmed with simulation examples.
