Search device for finding the direction of transmitters which emit a direction-finding signal

摘要

The invention relates to a search device for finding the direction of transmitters which emit a direction-finding signal and which are carried, for example, by those buried by avalanches, which search device comprises three antennas, each having a downstream receiving device. In order to receive the direction-finding signal from the transmitter 1, three magnetically sensitive antennas X, Y, Z, preferably ferrite rods, are each aligned at right angles to one another. The three receiving devices (reception devices 2, 3, 4) which are used to receive the respective antenna signals are connected, possibly via analogue/digital converters 16, to a computation circuit 5 which calculates the intensity M=root from (x 2 + y 2 + x 2)of the received transmitted signal. A display device (indicator) 6, at least for the values corresponding to the intensity, is connected to the computation circuit 5. IMAGE
