摘要: The results of the dispersion analysis spaced receiver records fading for an equatorial station in Indian zone are discussed. It is shown that apparent drift speed increases almost linearly with frequency all cases studied both E and F regions. larger region than general. Furthermore, shows a during daytime whereas it same order day nighttimes region. corresponding to highest Fourier present particular record found be close Va as determined from shift peak cross correllograms while total spread related random Vc derived by full correlation analysis. Several possible causes ionosphere such gravity waves, independently moving reflecting screens, height gradient horizontal size irregularities, dispersive nature vertical velocity, variability course Interference signals reflected two or more highly aspect-sensitive areas suggested mechanism resulting positive linear observed on ground at station.
