METHOD FOR REMOTE MEASUREMENT OF WIND SPEED AND DIRECTION Russian patent published in 2012 - IPC G01S13/95 

FIELD: radio engineering.

SUBSTANCE: reflector comprises a modulator-reflector 2, a system 3 of angle reflectors, a stabiliser 4 of plane of rotation of angle reflectors (a flag), a modulator support 5. The device to detect speed and direction of wind installed on a helicopter 6 comprises a transmitter 12, a duplexer 13, a transceiving antenna 14, receiving antennas 15 and 16, amplifiers 17, 22 and 23 of high frequency, a heterodyne 18, a mixer 19, an intermediate frequency amplifier 20, a meter 21 of amplitude modulation depth, multipliers 24, 25, 28, 36 and 38, bandpass filters 26 and 27, narrow band filters 29 and 37, a delay line 30, a phase detector 31, a phase meter 32 and 33, a reference generator 35, kinematically connected to a motor of the helicopter 34, a meter 39 of Doppler frequency and a processor 40.

EFFECT: higher accuracy and unambiguity of bearing measurement at a nonsetting reflector.
