Book Synopsis Estimation of the Cumulative Amplitude Probability Distribution Function of Ionospheric Scintillations by : H. E. Whitney
Download or read book Estimation of the Cumulative Amplitude Probability Distribution Function of Ionospheric Scintillations written by H. E. Whitney and published by . This book was released on 1971 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fading characteristics of ionospheric scintillations can be precisely described by a cumulative amplitude probability distribution function (cdf). The cdf expresses the probability or percentage of time that the signal amplitude will equal or exceed a given amplitude. Utilizing ionospheric scintillations observed on beacon signals from synchronous satellites transmitting at 136 MHz, distributions of amplitude variations have been made. The resulting distributions have been divided into five groups corresponding to ranges of scintillation index, the predominant measure in scintillation studies. The five distribution models are then combined with the occurrence of scintillations in various index ranges to produce cumulative amplitude probability distributions. These have been done for long term observations made at Hamilton, Mass., Narssarssuaq, Greenland, and Huancayo, Peru. The resulting data allows engineers to determine margins necessary for communication and navigation systems. (Author).

Book Synopsis High Latitude Models, Observations and Analysis of Ionospheric Scintillations by : Jules Aarons
Download or read book High Latitude Models, Observations and Analysis of Ionospheric Scintillations written by Jules Aarons and published by . This book was released on 1973 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to provide systems engineers with observations and analysis of the amplitude-fading of radio waves traversing the high latitude ionosphere, several different studies were performed. The concept was to develop descriptive and statistical models for the pattern of occurrence and amplitude of scintillations at high latitudes. Then, long terms observations from a limited number of sites could be linked to allow an assessment of the scintillation problem to communication, navigation, and detection systems in the VHF and UHF bands. This report discusses these studies in three chapters. In Chapter 1, general patterns of scintillation occurrence and intensity are presented in the descriptive model of the F-layer irregularities at high latitudes. This is followed in Chapter 2 by a graphical presentation of the data; that is, observations of the 136 MHz beacon of ATS-3. Chapter 3 organizes the observations into a useful format-the cumulative amplitude probability distribution function-for the engineer. A means of adjusting the observations for frequency dependence is provided.
Book Synopsis Notes on the Relationship of Scintillation Index to Probability Distributions and Their Uses for System Design by : H. E. Whitney
Download or read book Notes on the Relationship of Scintillation Index to Probability Distributions and Their Uses for System Design written by H. E. Whitney and published by . This book was released on 1974 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characterization of ionosphere scintillations in terms of scintillation index is discussed. Scintillation index cannot be directly applied to the design of systems that use transionospheric propagation. The relationships of scintillation index to system design parameters, cumulative amplitude distributions, and fade levels, are shown. The determination of a spectral index is explained and its use for extrapolating the results of ionosphere scintillation measurements to a desired frequency is shown.
