FIELD: radio engineering, communication.SUBSTANCE: direction-finder is in the form of three antennae with corresponding receiver-amplifier channels. Outputs of the receiver-amplifier channels of the antennae, which form a smaller base, are connected to corresponding inputs of a device for measuring phase shift of signal carrier frequency, the output of which is connected to the first input of a direction-finding information processing unit, and the output of one of the receiver-amplifier channels of the antennae is connected through a signal carrier frequency measuring unit to the second input of the direction-finding information processing unit. The direction-finder also includes a signal modulation envelope correlation metre, inputs of which are connected to corresponding detector outputs of the receiver-amplifier channels of the antennae which form a maximum base, wherein the output is connected to the third input of the direction-finding information processing unit.EFFECT: high accuracy of direction-finding.1 dwg |
