AN EXPERIMENTAL STUDY OF RAPID PHASE FLUCTUATIONS INDUCED ALONG A SATELLITE - TO EARTH PROPAGATION PATH,

Abstract

An experiment is described which has as its objective the examination of high-frequency phase fluctuations induced by the atmosphere along a satellite-to-ground propagation path. The phase fluctuations of interest lie in a spectral band ranging from approximately 0.1 cps to a maximum of 3 kc; the radio frequencies employed range from 54 to 400 Mc. The ionosphere-induced component of the observed phase fluctuation is of primary interest. Two classes of measurement are discussed; the first relies only upon use of a single highly stable sinusoidal emission from the satellite, whereas the second requires the emission of two harmonically related sinusoids, coherent with each other.
