摘要： Disclosed is in the present disclosure a dynamic compensation wind measurement lidar system, including a laser, an A/D converter, a signal processor, and a data processor. The signal processor includes a power spectrum calculation module, a motion sensor, and a pulse integration module. The pulse integration module divides an optical pulse transmitted in a single beam period into n sections for integration, where real-time motion and attitude data collected by the motion sensor is added to each of the sections for integration to improve a signal-to-noise ratio by integrating a power spectral density for a plurality of periodic pulse signals. In the present disclosure, by means of integrating optical pulses in single-beam dwell time by sections and attitude superimposing, an attitude compensation frequency may be greatly increased, and the attitude compensation frequency is adjustable.
