RADAR TRANSPONDER BEACON Russian patent published in 2014 - IPC G01S13/74 

FIELD: radio engineering, communication.

SUBSTANCE: invention is intended for use in a secondary radar system. The transponder beacon includes a three-channel interrogation signal receiver and an interrogation code and interrogator feature decoder connected to said receiver, a response signal former with a transmitter, wherein between the decoder and the response signal former there is a commutator switch for switching response triggering, interrogation pulse counters on each reception channel and each interrogator number, as well as an analyser of the number of interrogation pulses, wherein one input of the commutator switch is connected to the output of the decoder, the output of the commutator switch is connected to inputs of the counters, outputs of the counters are connected to the input of the analyser, the output of which is connected to the input of the response signal former.

EFFECT: enabling mutual orientation in a group of more than two mobile carriers equipped with radar transponder beacons.
