Embodiment Construction

[0043] A wind shear identification and tracking method based on a single-station wind profile radar, the specific steps are:

[0044] The first step is to build a wind profile radar wind shear identification and tracking system

[0045] The wind shear identification and tracking system of wind profile radar includes: data acquisition module, data preprocessing module, wind shear identification module and wind shear tracking module. The data acquisition module is used to collect wind profile radar detection data, the data preprocessing module is used to control the quality of wind profile radar detection data, the wind shear identification module is used for automatic detection and identification of wind shear, and wind shear tracking The module is used for automatic tracking and alarm of windshear.

[0046] In the second step, the data acquisition module collects wind profile radar detection data

[0047] The data acquisition module collects the detection data of the wind pr...

Abstract

The invention discloses a single station wind profile radar-based wind shear identification and tracking method. The method comprises establishing a wind profile radar wind shear tracking system including a data acquisition module, a data preprocessing module, a wind shear identification module and a wind shear tracking module; allowing the data acquisition module to acquire wind profile radar detection data; allowing the data preprocessing module to perform quality control on the wind profile radar detection data; allowing the wind shear identification module to perform wind shear automatic detection and identification; and allowing the wind shear tracking module to realize wind shear automatic tracking and warning. The inventive method has simple and easy implementation, high identification accuracy and full automatic operation, can obtain horizontal wind vertical shear information and vertical wind vertical shear information, and effectively detects and tracks wind shear start time, height and strength in the air above the station.

Description

technical field [0001] The invention relates to a wind shear identification and tracking method, in particular to a wind shear identification and tracking method based on a single-station wind profile radar. Background technique [0002] Wind profiler radar is a pulse Doppler velocity radar with atmospheric turbulence as the detection target and clear sky detection capability. It is mainly used to measure the change of wind with height. Because the wind profiler radar adopts remote sensing method, it can operate continuously unattended, and the detection data has many advantages such as various types, high temporal and spatial resolution, profile form, etc., it is playing a more and more important role in high-altitude (non-ground) wind detection. important role. A large number of observation data show that the shear line which affects flight safety has a clear performance in the continuous observation data of wind profiler radar. Therefore, it is of great significance to ...
