| 摘要 |
A locating device, particularly for locating trapped victims under avalanches, under debris or under collapsed buildings, equipped with a receiving unit ( 6 - 13 ) for signals from transmitters and preferably a transmitter ( 13, 14 ), as well as optical ( 6 ) and/or acoustic ( 12 ) display units, whereby the receiving unit is connected to three preferably orthogonally arranged ferrite rod antennas ( 2, 3, 4 ). All antennas ( 2, 3, 4 ) are disposed in a compact housing ( 1 ) together with the receiving unit ( 6 - 13 ) and preferably also the transmitter ( 13, 14 ) to ensure accurate locating of the trapped victim across the largest range possible at compact design whereby one antenna ( 4 ) is of substantially shorter length than the two other antennas ( 2, 3 ). The receiving unit is provided with a DSP module ( 11 ) for incoming signals of the antennas ( 2, 3, 4 ).
