Full Polarimetric Calibration for RCS Measurement Ranges: performance analysis and measurement results

摘要

Full polarimetric scattering measurements are increasingly being required for radar cross-section (RCS) tests. Conventional co- and cross-polarization calibrations fail to take into account the small amount of antenna cross-polarization that will be present for any practical antenna. In contrast, full polarimetric calibrations take into account and compensate for the cross-polarization the calibration process. We present a full polarimetric calibration procedure and a simulation-based performance study quantifying how well the procedure improves measurement accuracy over conventional independent channel calibration.
