Book excerpt: Data acquired with the Geophysics Laboratory's High Latitude Meteor Scatter Test-Bed between Sondrestrom Air Base and Thule Air Base. Greeland during the solar disturbances of March and August, 1989 are presented. These events provided a unique opportunity to observe a number of naturally occurring disturbance effects on meteor scatter links operating in the frequency range (35 to 147 MHz) covered by the test-bed. The effects range from signal absorption to system noise variations. The properties of ionospheric absorption in general is discussed and illustrated with computations using electron density profiles from the September 1978 Solar Proton Event (SPE). It has been found that accurate measurements of high levels of ionospheric absorption with riometers pose special problems. These problems are identified and discussed. The data acquired during the March and August solar disturbances are then related to the zenith absorption measured at Thule, and the influence of absorption, as well as system noise variations are discussed.

This book was released on 1986 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: High latitude propagation phenomenon such as scatter from the aurora and sporadic-E propagation can alter the communication characteristics of the high latitude meteor communication channel. This report describes the results of several experiments conducted for the purpose of characterizing the fading and multipath profile of the high latitude meteor communication channel. The effect of high latitude propagation phenomena on the capacity and reliability of meteor burst communications is discussed. Keywords include: Auroral scatter, Meteor scatter high latitude effects, multipath measurements, meteor scatter communications, and VHF propagation.

Download or read book Performance Statistics Bulletin. High Latitude Meteor Scatter Propagation February, March, April, May 1990 written by and published by . This book was released on 1994 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: A representative sampling of meteor scatter propagation performance statistics is presented from the PL/GP High Latitude Meteor Scatter Test Bed. The data address questions of meteor scatter propagation under disturbed ionospheric conditions, as well as normal meteor scatter propagation in the polar region. The time and frequency variations of the propagation transfer function are characterized over the 35 to 147 MHz range, including the availability of useful meteor trails, the potential communication capacity associated with those trails, the occurrence and persistence of ionospheric scatter and sporadic E-layers, variations in the signal-to-noise ratios of each scatter return and the effects of auroral and polar cap absorption (PCA) events on meteor scatter propagation and communications. Statistics covering Arrival Rate, Duration, Duty Cycle, and Noise Temperature are presented. This bulletin is one of a series covering the test bed operation from February 1990 through September 1992. Meteor scatter, Communications, High latitude propagation, Propagation.
