DEVICE MEASURING TIME POSITION OF AZIMUTHAL SIGNAL OF RADIO SYSTEMS OF SHORT-RANGE NAVIGATION

摘要

FIELD: radio navigation. SUBSTANCE: device measuring time position of azimuthal signal of radio systems of short-range navigation has filter which output is connected to measurement input of time interval hold circuit, peak detector and divider connected in series and computer of symmetry center of time interval. Input of peak detector is connected to output of filter, output of divider is connected to setting input of time interval hold circuit which output is connected to computer of symmetry center of time interval. Filter has rectangular amplitude-frequency characteristic. EFFECT: increased precision of measurement of time position of azimuthal signal of various duration under instability of level of holding and action of fluctuation noise on input of time interval hold circuit.
