Structure of density fluctuations near the sun deduced from Pioneer-6 spectral broadening measurements

摘要: In this paper we present an analysis of the spectral broadening monochromatic radio waves by density fluctuations near Sun using parabolic equation method. Application to 1968 Pioneer-6 observations yields indirect measurements spectrum within 14 R/sub sun/ Sun. For spatial wavenumbers kappaapproximately-greater-than8.4 x 10/sup -3/ km/sup -1/, three-dimensional is found be close Kolmogorov (power law with index p=11/3) and consistent IPS (interplanetary scintillations) in situ spacecraft farther from The magnitude increases but shape remains same during ''solar events'' marked bandwidth.
