SEISMIC TRANSMISSION TESTS:VIBRATORY SOURCE

摘要

As a part of the Sandia Laboratories' Plowshare program to study the feasibility of through-the earth communication systems, a vibrator, capable of introducing sinusoidal signals into the earth, was tested at the Nevada Test Site in February 1972. The tests were conducted to determine at what depth and slant range signals could be detected. The tests showed adequate signal-to-noise ratios at depths of 4400 feet (the maximum hole depth) and slant ranges over 8100 feet.
