PHASE DIRECTION FINDER Russian patent published in 2017 - IPC G01S3/46 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in radio monitoring when searching for radio-frequency radiation sources within confined territory and in premises, for example, special electronic information interceptors. Said result is achieved due to introduction of the fourth adder, connected via the first direct input with output of the second phase changer, and via the second direct input with output of the third controlled phase changer, fifth adder, connected via the first direct input with output of the second phase changer, and via the second inverting input with output of the third controlled phase changer, second subtractor, connected via input of subtrahend through the third device of calculation module with output of the fourth adder, and via input of subtrahend through the fourth device of calculation module with output of the fifth adder, sixth adder connected via the first and second uncomplemented inputs with outputs of the third and fourth calculation devices of module, respectively, second amplifier, connected via input with the output of the second subtractor and output of the second base limiter at zero level simultaneously, second comparator, connected via the first input with output of the sixth adder, and via the second input with output of the second amplifier. Output of the second comparator is the second output of the phase direction finder.

EFFECT: achieved technical result – possibility of using direction finder to determine angular position of radio-frequency sources simultaneously in two orthogonal planes.
