Three-Antenna Polarization Measurements Again

This paper extends a 2020 AMTA paper [1] in which we simulated (with added noise) an older, and seemingly forgotten, technique for processing three-antenna polarization data that uses well known signal processing algorithms. Here we analyze actual measured data. Topics explored include: (1) Fourier filtering, (2) bidirectional S-parameter measurements, and (3) time-domain gating. We demonstrate a robust approach that is effective and easy to implement.
