DEVICE FOR MEASURING COMPONENTS OF TRACK SPEED VECTOR Russian patent published in 2020 - IPC G01S13/60 

FIELD: navigation systems.

SUBSTANCE: invention can be used in on-board navigation systems. Technical result is achieved due to that device for measuring components of track speed vector comprises a certain high-frequency filter, low-noise amplifier, band-pass filter, power amplifier, directional coupler, divider, circulator, preamplifier, frequency mixer, low-pass filter, differential line driver, SHF switch, transceiving antenna, controller, analogue-to-digital converter, microcontroller, random-access memory, a signal switch, a control register, a super-high frequency generator, a preamplifier, an analog filter, a complex multiplier, a quadrature signal generator and complex reference signals, a low-pass digital filter with signal decimation, a fast Fourier transform unit, module for converting harmonics by module with subsequent combination of two channels, threshold circuit, Doppler detection circuit, status register, test signals generation circuit.

EFFECT: technical result is higher reliability and safety of aircraft piloting.
