FIELD: radio engineering, applicable for determining the radio signal bearing and frequency in radio-engineering monitoring systems.
SUBSTANCE: the device has two frequency converters, controlled local oscillator and two phase-difference meters connected to one another and the other elements of the device in a definite way, the focal axes of the reception antennas used in the claimed device are parallel, the centers of the antenna are spread at a distance approximately exceeding the wavelength of the controlled radio signal by an order, and the width of the directivity pattern of each antenna makes up 180 deg.
EFFECT: simplified construction and enhanced accuracy of direction finding.
