METHOD AND DEVICE FOR MEASURING WIND SPEED AND AIR TEMPERATURE IN ATMOSPHERIC BORDER LAYER Russian patent published in 2017 - IPC G01W1/02 G01S17/87 G01P5/00 

FIELD: measuring equipment.

SUBSTANCE: device contains a ground module and an altitude module placed on board of unmanned aerial vehicle (UAV). The following elements are included in the ground module: the clock-pulse generator (1), the time interval meter (2), the calculating unit (3), the coordinate decoder (4), the acoustic pulse source (5) of the first pair of acoustically matched sources and acoustic pulse receiver, the emitter (6) of electromagnetic pulses, the receiver (7) of electromagnetic pulses, the receiver (8) of acoustic pulses of the second pair of acoustically matched source and receiver of acoustic pulses, the receiver (9) of code signals. The following elements are included in the composition of the altitude module: the receiver (10) of acoustic pulses of the first pair of acoustically matched sources and acoustic pulse receiver, the electromagnetic pulse receiver (11), the electromagnetic pulse emitter (12), the acoustic pulse source of the second pair of acoustically matched sources and a receiver for acoustic pulses (13), the transmitter (14) for code signals, the UAV position determining unit (15). Sounding points X₁ and X₂ are selected so that the point X₁ was at the planned altitude of the meteorological parameters control, and the point X₂ on the earth surface. Wherein the line passing through the points X₁, X₂, should not be orthogonal to the plane of the earth's surface. Single acoustic and electromagnetic pulses are synchronously emitted from the point X₂. At the point X₁ said acoustic and electromagnetic pulses are recorded. By the difference in the arrival time of pulses to the point_X1the propagation time of acoustic pulse along the X₂-X₁ is determined. Single acoustic and electromagnetic pulses are synchronously emitted from the point X₁. At the point X₂ said acoustic and electromagnetic pulses are recorded. By the difference in arrival time of pulses to the point X₂ the propagation time of the acoustic pulse along the X₁-X₂ is determined. Average wind speed and temperature are calculated along the route X₁-X₂.

EFFECT: increase the range of measurements, reduce the dependence of measurements on meteorological conditions, increase the noise immunity of measurements.
