    Using of H-field antennas in system for searching of people under avalanches
    (Видавництво Національного університету "Львівська політехніка", 2009) Shirokov, I. B.; Durmanov, M. A.
    Some aspects of creation of system for searching of people under the rock’s obstruction, avalanches, and construction’s ruins are considered. Taking into account the impossibility of use of standard antenna’s systems on working frequencies and on working distances the using of inductance coils for signal’s reception and signal’s transmitting was offered. In this case due to the mutual induction between the coils it is possible to establish the communication and it is possible to estimate the distance up to object of search. Owing to properties of a magnetic field the choice of mutual positioning of the coils by a method of a maximum is possible. With using of H-field antennas in system for searching of people under avalanches the positioning of objects of searching is possible.
