METHOD OF MEASURING WIND VELOCITY Russian patent published in 2016 - IPC G01S13/95 G01P5/00 

FIELD: measurement technology.

SUBSTANCE: invention relates to methods for remote analysis of atmosphere based on use of Doppler effect and use of phase-shift keyed signals, and can be used for measurement of wind velocity. Method is carried out using a device including drive, receiving channels (1, 2, respectively) and range selection channel (3). Drive channel (1) generates radiation frequency of oscillations f₀, which binary phase-shift keyed with a pseudorandom sequence with duration T with elementary signal T_e. T/T_e=N*, where N* is sampling rate of measurement transmissions in time. Simultaneously in drive channel (1) is generated a similar signal with frequency shift f₀+f_cm, that of type FM_N(f₀+f_cm). Input reflected signal has frequency type f₀+f_Doppler. Input reflected signal is multiplied in first case with output signal τ range, and in second case - τ range + $$\frac{\pi }{2}$$ , thus for selected range τ delay is eliminated by phase-shift keying and continuous signals are generated. After multiplication signals are generated and their envelopes are integrated at frequencies f₀+f_Doppler for not less than duration T. After that channel with maximum amplitude of signal with maximum Doppler frequency is determined, corresponding to wind velocity at selected distance.

EFFECT: measurement of wind velocity.
