Two-Way Frequency Fluctuations Observed During Coronal Radio Sounding Experiments

Pätzold, M.; Bird, M. K.; Efimov, A. I. +5 more

Coronal radio-sounding experiments were carried out using two-way coherent dual-frequency carrier signals of the ESA spacecraft Rosetta (ROS) in 2006. Frequency measurements recorded at both NASA and ESA tracking stations (sample rate: 1 Hz) are analyzed in this work. Spectral analysis of the S-band, X-band, and differential frequency records has …
