Strong intensity spectra were observed simultaneously by Vats (1981) on transmissions through the ionospheric F-region at 40, 140, and 360 MHz from a stationary satellite. These spectra are explained quantitatively in terms of refractive scattering, using the approach of Booker and MajidiAhi (1981). The outer and inner scales are 50 km and 5 m, respectively, and the integrated mean square fluctuation of ionization density is 10 to the 28th/m. The spectral index of three produces the correct spectral behavior at high fluctuation frequencies, and the correct ratios of the upper roll-off frequencies at three wave frequencies. The rms fluctuation of phase is about 130 rad at 360 MHz, 340 rad at 140 MHz, and 1200 rad at 40 MHz. At 40 MHz, the scale of the intensity fluctuation at ground level is about 10 m; removal of almost all fluctuations in the ionosphere at scales below the Fresnel scale leaves the fine structure of the intensity spectrum at ground level virtually unaffected.
