PHASE DIRECTION-FINDER Russian patent published in 2009 - IPC G01S3/46

Abstract RU 2362179 C1

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in systems of radio environment monitoring at complex level or as self-contained unit. Applied phase direction-finder contains two antennas, two high-frequency amplifiers, phase detector, logarithmic video amplifiers, analog adder, analog-to-digital converters, pulse detectors, phase difference calculator, power code generating unit, correcting code generating unit and digital adder interconnected in a certain manner. Distinctive feature of direction-finder construction is the following: due to use of post-phase detector of logarithmic video amplifiers detection of superimposed pulse signals, pulse signal against continuous interference and simultaneous measurement of direction-finding bearing, power and duration of input signal become possible.

EFFECT: increase of interference immunity and enhancement of functionality.
