The Cassini solar Faraday rotation experiment

摘要: Abstract The Cassini Faraday rotation experiment improves the current understanding of coronal magnetic field by making first measurements within two solar radii south pole and allowing separation changing electron density from during transient crossings line sight. Simultaneous ranging data to also contributes growing body empirical models providing at maximum varying latitudes including over poles. in corona were collected 2002 2003 using spacecraft cruise Saturn. Although primarily transmits right-hand polarization, enough left-hand is produced enable polarization measurements. We show that conjunction measurable with Cassini. In X- Ka-bands both datasets currently an asymmetric diurnal pattern not associated ionosphere. Ka-band much more sensitive pointing accuracy experienced periods power drop outs which caused left-circularly polarized signal into noise on occasion conjunction. Interpretation dataset deferred future papers.
