DEVICE TO DETERMINE DIRECTION AT SIGNAL SOURCE Russian patent published in 2013 - IPC G01S3/02 

FIELD: measurement equipment.

SUBSTANCE: device to determine direction at a signal source comprises three reject filters, three low pass filters, three amplifiers, three analogue-to-digital converters, three receivers, a personal computer, three calibrators, a clock oscillator, two delay lines, a summator, a frequency synthesiser, four logical AND circuits, three registers, three mixers, three narrowband filters, an antenna unit, a synchronisation device, a communication unit, a logical OR element, a comparator, a counter, a limiter, a detector, a setter, two synchronous detectors. At the same time the communication unit and the synchroniser are made as capable of linking information to unified time due to reception of GPS or Glonass signals, and the third signal is made jointly with a phase changer.

EFFECT: possibility to quickly select sources of signals by width of a radiated spectrum or to quickly select frequency zones that are free of signals.
