Underground Radio Communications and Radio Observation

Boris Levin


The problems of underground radio communications and radio observation are considered. The need for radio communication with people working underground is especially obvious during underground accidents. Radio observation makes it possible to monitor underground channels to detect their changes, caused, for example, by underground tunnel construction work in the border zone. Solving these problems is complicated by the sharp weakening of the signal in the ground and the presence of an interfering parallel signal propagating above the ground. Options for antennas to solve the described problems and methods for dealing with interfering signals are proposed. Receiving and transmitting centers for placing antennas are described.
