Technical Evaluation Report on the Electromagnetic Wave Propagation Panel Symposium on Propagation Effects on Military Systems in the High Latitude Region

摘要

This document summarizes the meeting and discusses the varied papers presented as well as the post-meeting round table discussion. Conclusions are drawn and recommendations put forth. This meeting was held to bring together ionospheric physicists, communications and systems engineers, plus managers and users of communications and surveillance systems from the NATO countries to exchange information on the subject of the symposium. Included in the scope of the meeting were: (1) detailed experimental studies of ionospheric irregularities and regular structure, (2) results of ionospheric modification (HF heating) experiments, (3) theoretical studies of ionospheric irregularity formation, (4) a global survey of ground conductivities, (5) results of disturbance modeling studies, (6) high latitude effects on the following systems: a) HF radio communication, b) trans-ionospheric communications, c) Satellite synthetic aperture radar (SAR), d) MF radio broadcasting, e) Spatially adaptive propagation, f) HF digital, g) Skywave HF sea-state radar and h) meteor burst communication. Keywords include: Electromagnetic wave propagation, Propagation effects, High latitude, Incoherent scatter studies, Geophysical, Irregularity structure, Radiowave propagation, RF spectrum, Magnetosphere, and Geomagnetic.
