DETECTOR OF POLARISED ANOMALY OF UPWELLING RADIATION OF EARTH Russian patent published in 2009 - IPC G01V9/00 

FIELD: mining.

SUBSTANCE: detector installed on space carrier includes on-board control complex connected to tracking headquarters, chains of microwave frequency receiving, channel of information transmission to earth points and processing chain. Also two spiral aerials with rotating polarisation of the right and left direction of rotation are introduced into the detector. Each of aerials is connected to an input of one of the parallel receiving chains. Outputs of receiving chains are loaded onto opposite arms of a differential bridge circuit. The output of the differential bridge circuit is connected with the input of successively attached: a threshold circuit, an analogue-digital converter and a recording device, all connected with the on-board complex of control.

EFFECT: facilitating efficient and veritable prognosis on base of received registering graphs of measurements over site zone round-the clock and in all-weather.
