Abstract

The present invention belongs to the meteorological measurement field and relates to a wind field measurement method and device. The wind field measurement method includes the following steps that: flight number information, ADS-B position information and ADS-B vacuum speed information in ADS-B data are extracted; flight number information, SSR position information and SSR vacuum speed information in SSR data are extracted; a fusion ground speed vector is generated; and horizontal wind speed vectors at different observation time points are obtained according to the ADS-B data and the SSR data, so that a wind field can be obtained through fusing the horizontal wind speed vectors. According to the wind field measurement method and device of the invention, data fusion is performed on the ADS-B data and the SSR data, so that aircraft ground speed measurement precision can be improved; the SSR data are adopted, a coverage area of a mode according to which wind field measurement is carried out by means of ADS-B data alone can be increased; and the ADS-B data are adopted, and the temporal-spatial resolution and accuracy of a mode according to which wind field measurement is carried out by means of SSR data alone can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of meteorological measurement, and in particular relates to a wind field measurement method and device. Background technique [0002] Wind field measurement has a wide range of needs in meteorology, agriculture, forestry, aerospace, maritime and other fields. The existing high-altitude wind field measurement methods mainly include sounding balloons, wind profile radars, and laser wind radars. The time resolution of sounding balloons is low and cannot provide efficient and real-time wind field measurement data; Radar is expensive, the measurement model has certain assumptions, and the detection capability is easily affected by weather conditions. Contents of the invention [0003] Aiming at the current problems of low time resolution of wind field measurement and detection capability easily affected by meteorological conditions, the present invention proposes a wind field measurement method and device. Th...
