The paper considers the shape of the power spectrum of ionospheric electron-density fluctuations required to explain observed power spectra of amplitude and phase fluctuations at several frequencies. The amplitude and phase spectra are estimated theoretically for two weak-scattering models, and scintillation observations are analyzed which were made using phase-coherent transmissions at 150 and 400 MHz from U.S. Navy navigation-system satellites and receivers. The results show that the Rytov approximation provides a reasonable description of scintillation over a wider range of scintillation intensity than does the Born approximation to the wave equation, and that the log amplitude, phase description of scintillation is to be preferred over the in-phase, quadrature amplitude description. It is also found that the Doppler spread and rms phase fluctuations vary as the first power of wavelength for both strong and weak scintillation. The experimental observations are shown to be consistent with a power-law model having a slope of -3 and an exponent of 4.
