Available in PDF, EPUB and Kindle. Book excerpt: The report supplements earlier attempts at modelling. Its elements are the result of a group effort, which is continuing. The arctic ionosphere and its dynamics are described as a fairly self-consistent empirical quasi-instantaneous model, adaptable to later improvements. The definitions are in analog form using model, adaptable to later improvements. The definitions are in analog form using tables, graphs, and analytical formulas. The model parameters controlling the arctic ionosphere are substorm time and intensity and oval number Q. Emphasis is given as to how those parameters may be obtained in near-real-time. For this purpose, two superimposed coordinate systems and two reference latitudes are introduced. The model assumes absence of sunlight; it provides rules for adding the sunlit contribution and for matching the arctic model to the moderate-latitude ionosphere. (Author).

Book excerpt: A statistical analysis of Alouette topside ionograms shows that the probability of occurrence of the midlatitude F-layer trough is 100 percent in winter and at equinox, and is 50 percent in summer. The trough, which is generally centered on 55 degrees corrected geomagnetic latitude and which is about 5 degrees to 10 degrees wide, extends throughout the night hemisphere with f(o)F2 values less than 2 MHz. Comparison of the location of the trough to the area in which coverage by an over the horizon backscatter (OTHB) system is anticipated shows that the trough will adversely affect system performance in the northeast direction most of the night. An in-depth case study of the effects of the trough on HF propagation was made, based on an instantaneous three-dimensional description of the ionosphere. This description of the ionosphere was composed of cross sections showing ionospheric electron-density structure in the area northeast of the Polar Fox II site. Three-dimensional raytracing was applied to this description of the ionosphere, and the trough and the steep electron-density gradient at the poleward edge of the trough were found to adversely affect propagation of HF signals.

This book was released on 1975 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swept-frequency traces of minimum group-path length in backscatter-radar ionograms, computed for a measured three-dimensional electron distribution in the midnight sector of the polar ionosphere, are presented. Also presented are minimum group-path traces computed for trial electron distributions chosen to simulate the group-path traces of the measured electron distribution, and to show the effects on the group-path traces as consequences of variations made upon major features of the trial electron distributions.

Book Synopsis Ray-tracing Simulation of Swept-frequency Backscatter Ionograms by : Ming S. Wong
Download or read book Ray-tracing Simulation of Swept-frequency Backscatter Ionograms written by Ming S. Wong and published by . This book was released on 1974 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computed swept-frequency traces of minimum group-path in backscatter-radar ionograms are presented for ionospheric electron distributions in the polar region. Some of the traces for ground backscatter contain cusps that are shown to result when a small fraction of rays from the radar encounter a region in which the vertical electron-density gradient decreases sharply with distance after the rays passed through apogees. An accurate geomagnetic field model is used in obtaining traces for direct backscatter from field-aligned ionization that causes radar auroral clutter. A method is described for representing three-dimensional electron distributions. The method is sufficiently flexible for iterative ray computations, which appear as a reasonable and potentially reliable approach to the problem of converting backscatter-radar ionograms to electron distributions.
