A receiver for a phase system of short-range navigation includes a synchronizer, connected in series receiver and detector, connected in series first filter of sub-carrier frequency, first amplifier – restrictor, first frequency discriminator, first low frequency filter and phasometer, and the low frequency second filter which output is connected to the second input of the phasometer. To increase accuracy of measurement of phase difference between the reference and variable signals of the radio-beacon introduced are a switch, random access memory, subtraction block, connected in series second filter of sub-bearing frequency, second amplifier – restrictor, second frequency discriminator, third low frequency filter and adder which output is connected to the first input of the switch, and connected in series generator of reference oscillations and frequency modulator which output is connected to the second input of the adder. |
