Abstract:

A phase screen simulation experiment is designed and implemented to model radio occultation through sporadic-E ionospheric disturbances between a GPS transmitter operating at the L1 frequency and a second receiving satellite in low earth orbit LEO. Simulations were made to test the linear relationship between plasma intensity and scintillation S4 index both posited Arras and Wickert, 2018 and contended Gooch et al., 2020 in previous literature. Results brought into question both the linear relationship and the use of S4 as a whole and an alternate metric was sought.
