Channel Characterisation and System Design for Sub-Surface Communications

Meer over het boek

Focusing on subterranean radio communication, this theoretical study explores electromagnetic field penetration through the ground. It highlights applications in mining search and rescue, borehole telemetry, and pipeline location. Key topics include signal propagation, antenna design, and transmitter/receiver construction, introducing a figure of merit called specific aperture to aid in antenna design. The book emphasizes the importance of signal-to-noise ratio and presents strategies like noise-matching, along with a detailed design for a wide-band low-frequency sounder for channel evaluation.
