ELF/VLF/LF Radio Propagation and Systems Aspects (La Propagation des Ondes RadioELF/VLF/LF et les Aspects Systemes)

摘要

This publication reports the papers presented to a specialists' meeting held bythe Electromagnetic Wave Propagation Panel at its Fall 1992 meeting. The topics covered on the occasion of that symposium include: Propagation aspects; Numerical modelling; Propagation measurements; and Propagation in sea water. Radio noise and interference; Long wave TE/TM Noise prediction model; Measurements; and ELF generated by auroral electrojet modulation. Antenna considerations; Antenna fundamentals; Scale modelling; Measurements of pattern and bandwidth; and Tethered aerostat VLF/LF transmitting antennas. System aspects; Viability assessment for reliable LW communication links. Future satellite systems; Orbiting system for ELF/VLF strategic communications, and Tethered satellite systems....
