PHASE RADIO DIRECTION FINDER Russian patent published in 2010 - IPC G01S3/46 

FIELD: physics.

SUBSTANCE: phase radio direction finder has two receivers, each fitted with an antenna, the output of the first receiver is connected to the first input of an adder and the first input of a subtractor, the second input of each of which is connected to the output of the second receiver, the output of the subtractor is connected through a first amplitude detector to the first input of a logic processing device, the output of the adder is connected through a second amplitude detector to the second input of the logic processing device, wherein there is also a frequency metre, a differentiator and a clock-pulse generator, wherein the input of the frequency metre is connected to the output of the second receiver, and the output - to the third input of the logic processing device and through the differentiator to the input of the clock-pulse generator, whose output is connected to the fourth input of the logic processing device, whose output is the output of the phase radio direction finder.

EFFECT: unambiguous measurement of coordinates of a radiation source.
