PHASE DIRECTION FINDER Russian patent published in 2002 - IPC

FIELD: radiolocation, radio navigation, applicable for determination of angular co-ordinates of the source of radiation of a phase-manipulated signal. SUBSTANCE: phase direction finder has the first 1, second 2 and third 22 receiving antennas, the first 3, second 4 and third 23 receivers, the first 5, second 6, third 14, fourth 24 and fifth 30 multipliers, the first 7, second 8 and third 25 narrow-band filters, phase shifter by 90 deg, the first 10 and second 26 phase detectors, the first 11, second 16, third 27 and fourth 32 indicators, the first 12 and second 28 correlators, the first 13 and second 29 adjustable delay units, the first 15 and second 31 low-pass filters, the first 18 and second 34 measuring instruments, the first 17 and second 33 extreme regulators. EFFECT: expanded functional capacities of the direction finder due to direction finding of the source of radiation of a phase-manipulated signal in space and estimation of its parameters. 5 dwg
