The broadband phase radio direction finder for coordinate determination of radiation sources of harmonic signals

Abstract

The present paper concerns the circuit implementation of a phase radio direction finder for coordinate determination of radiation sources with harmonic signals. The use of sparse linear antenna arrays and radiation source are examined. The feature of this radio direction finder is an ability to operate in the frequency band. The basic relations for the direction-finding characteristics, which allow providing the operation of the radio direction finder in the frequency range using measured wavelength and implementation of the demodulation unit on broadband quadrature bridges.
