Abstract: This article presents a novel constellation modeling method for fast and accurate calibration of beamforming integrated circuits (BFICs) and radio frequency (RF) chains in large-scale phased ...
In the nearby galaxy NGC 4258, the well-modeled orbital motion of H2O masers about its supermassive black hole provides the means to measure a precise geometric distance. As a result, NGC 4258 is one ...
Abstract: The calibration for a large phased array requires a significant amount of measurements using existing calibration methods. To accelerate the calibration process, this article proposes a ...
