摘要:
A through-the-earth (TTE) communication system has a transmitter that uses an electromagnetic antenna to propagate a magnetic communication signal through the earth. The antenna comprises a coil that is wrapped a core of magnetic material. The transmitter converts voice into a pulsed direct current (DC) signal that is applied to the coil of the antenna. The antenna transforms the pulsed DC signal into a pulsed DC magnetic field that propagates through the earth, and the DC magnetic field may pass through soil, water, or other substances within the earth. A receiver at the earth's surface or other location senses the pulsed magnetic field and converts the sensed magnetic energy into a voice signal.
