Title:
LASER RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/152863
Kind Code:
A1
Abstract:
A laser radar device according to the present disclosed technique scans a laser and measures the wind speed field of an observation environment, the laser radar device comprising a signal processing unit (13) that includes a spectral transform processing unit (13a), an integration processing unit (13b), a wind speed field calculating unit (13d), and a learning algorithm unit (13e), wherein: the spectral transform processing unit (13a) performs an FFT process on beat signals that are digital signals in a time series state and generates spectral data; the integration processing unit (13b) performs integration processing on the spectral data; the wind speed field calculating unit (13d) calculates a wind speed field on the basis of the information about the data processed by the integration processing unit (13b); and the learning algorithm unit (13e) is provided with trained artificial intelligence and interpolates observation results on the basis of the information about the wind speed field.
