RADIO-WAVE FLUCTUATIONS IN SATELLITE-ATMO SPHERE-SATELLITE LINKS - ESTIMATES FROM STELLAR SCINTILLATION OBSERVATIONS AND THEIR COMPARISON WITH EXPERIMENTAL-DATA

Relations are obtained to calculate the stratosphere-caused statistica l characteristics,of radio wave fluctuations for a satellite-atmospher e-satellite link on the basis of stellar scintillation observations. T he method of preliminary stationarization of optical data is proposed and used to extend the bandwidth of spectral analysis. The estimates o f the variances and power spectra for the fluctuations of amplitude, p hase, and refraction angle of radio waves of both centimeter and decim eter ranges are obtained. These estimates are compared with the result s of a radio occultation experiment in the earth's atmosphere [6]. The calculated estimates are noted to be in agreement with the experiment al data obtained at a wavelength of 2 cm.
