DYNAMIC COMPENSATION WIND MEASUREMENT LASER RADAR SYSTEM AND WIND MEASUREMENT METHOD THEREFOR

摘要

Disclosed in the present invention is a dynamic compensation wind measurement laser radar system, comprising: a laser device, an A/D converter, a signal processor and a data processor; the signal processor comprises a power spectrum calculation module, a motion sensor and a pulse accumulation module; the pulse accumulation module divides light pulses emitted in a single light beam period into n segments for accumulation, adds real-time motion and posture data acquired by the motion sensor to each segment of accumulation, and accumulates power spectrum density of pulse signals in multiple periods, so as to increase the signal-to-noise ratio. In the present invention, by means of segmented accumulation of the light pulses in the single-light beam residence time and posture superimposing, the posture compensation frequency can be greatly increased, and the posture compensation frequency is adjustable.
