FIELD: measuring equipment.
SUBSTANCE: using for remote measurement for remote measurement of wind speed and direction. Invention gist is that doppler scanning lidar of an onboard basing system contains: a semiconductor laser; divider; fiber-optic amplifier; acousto-optical modulator; multistage fiber-optic amplifier; optical circulator; receiving-transmitting telescope; a scanning unit; fiber optic combiner; balanced detector and microprocessor. Scanning unit is configured to provide the direction of the optical axis of the lidar output radiation in a predetermined mode, scanning unit consists of two prisms deflecting the optical axis of the lidar output radiation, depending on their position relatively to each other, prisms are made in the form of silicon wedge-shaped plates, which are rotatable about the axis of the telescope passing through their center.
EFFECT: increasing the efficiency and accuracy of measuring speed and determining the direction of air masses movement and detecting dangerous wind phenomena.
