The authors present a multistatic imaging system at microwave frequencies based on arrays of planar cavity sub‐apertures, or panels. imager consists sets transmit and receive panels, loaded with radiating irises distributed over the sub‐apertures in an aperiodic pattern. This frequency‐diverse aperture produces distinct radiation patterns as function frequency that encode scene information onto set measurements; images are subsequently reconstructed using computational approaches. Similar to previously reported systems, cavity‐based presents simple architecture, minimising number expense components required traditional systems. builds previous approaches, such recently metamaterial air‐filled by utilising panels for both system. Though panel‐to‐panel architecture has greater sensitivity calibration error, this implementation nevertheless increases mode diversity and, context system, results improved image reconstructions.
