    © 2017 Euraap. We demonstrate a frequency-diverse imaging system using an air-filled cavity-backed antenna as a transceiver (cavity-to-cavity system layout) for the K-band (17.5-26.5 GHz) frequency regime. Leveraging the computational imaging concept, the frequency-diversity enables imaging in an all-electronic manner, without the need for mechanical raster scanning or active circuit components, minimizing the data acquisition time and simplifying the system architecture. It is shown that the proposed system is capable of reconstructing good fidelity images in a sub-second time frame, holding significant potential for real-time imaging applications.
