Abstract
The use of GPS occultations to detect upper level atmospheric turbulence is presented. Given a set of assumptions, scattering theory gives the form for the phase and amplitude power spectra. Using these methods, along with the assumptions of a von Karman spectrum and the thin screen approximation for the index of refraction fluctuations, a formula is derived that shows that the spectra of the phase and amplitude fluctuations are proportional to the structure constant of the index of refraction fluctuations and the thickness of the turbulent patch. These results are then compared to measured GPS occultation data, indicating that the fluctuations in the GPS signals are consistent with the turbulence model.
