Polarimetric Weather Radar Calibration by Computational Electromagnetics

摘要

The paper proposes a technique for calibrating a large polarimetric phased array weather radar The focus is on the use of computational electromagnetics. It validates the accuracy of the computations on a scaled-down antenna model and derives calibration parameters for the same model. The proposed technique is demonstrated using the WIPL-D software. The calibration is illustrated with all mathematical concepts required to carry the calibration out. The concept is adapted to use the results of numerical simulations which is part of the paper's novelty. Additionally, a roadmap of polarimetric phased array calibration is proposed and illustrated.
