In this work we present calibration approaches aimed at mitigating the measurement error in testbenches featuring multiple sensor-nodes and operating over-the-air. Such errors can arise from fluctuations in component responses and mechanical tolerances of the setup. The calibration approaches are detailed for the case of the Antenna Dome...

The continuous advancements in the coverage and sensitivity of terahertz direct-detector imagers places increasing constraints on the test benches needed for characterization. Already, relative differences on the order of a few decibels are observed between simulated and measured performance in the state-of-the-art literature. This...

The recent development of commercial phased array antennas for 5G at mm-wave frequencies (20 GHz to 60 GHz) introduces new challenges for radiation pattern characterization. Since these systems aim to employ active beamforming to steer the datastream to specific users, a single base station should be capable of deploying multiple beams...

Recent advancements in Multiple-Input Multiple-Output (MIMO) radar techniques has created a paradigm shift in the overall radar technology to increase degrees of freedom in multi-function radar capabilities. The underlying principle of MIMO transmissions is to transmit independent waveforms from each antenna-element which do not interfere with...
