UA64705U - Broadband phase radio direction finder - Google Patents

Abstract

Broadband phase radio direction-finder includes three antennae placed in one plane by straight line at multiple-values bases, three identical receivers, block of demodulation of signals that has four outputs and block of logical processing, at that the outputs of the antennae are connected to the inputs of respective receivers, the outputs of the first and third receivers are connected to the first and the fourth inputs of demodulation block, it includes as well frequency meter and eight analog-digital transformers. At that demodulation block is arranged on two broadband phase splitters and eight adders with two inputs and eight amplitude detectors, and block of logical processing is arranged as a microprocessor, at that the inputs of the demodulation block are inputs of the phase splitters, sixteen outputs of which are connected to respective inputs of the adders, eight outputs of those are connected to the inputs of amplitude detectors, and outputs of those – to inputs of analog-digital transformers outputs of which are connected to the first eight outputs of the microprocessor. Input of the frequency meter is connected to the output of the second receiver, and its output is connected to the ninth input of the microprocessor output of which is output of the direction finder.
