Method for acquiring three-dimensional wind field by using wind profiler radar

Abstract

The invention discloses a method for acquiring a three-dimensional wind field by using a wind profiler radar. The method is characterized by comprising the following steps of: firstly, acquiring radar-based data by using the wind profiler radar; secondly, feeding the acquired data into a computer for preprocessing; thirdly, picking a spectrum center of each library by the preprocessed data near wave beam and the distance library and calculating parameters; and fourthly, generating a three-dimensional same field by adopting a defined amount synthesizing method according to the calculated parameters. The invention solves the problems that a power spectrum center cannot be picked correctly in the wind profiler radar wind field and also solves the problem of how to effectively synthesize the wind field. The invention greatly reduces the interference of the inversed wind field information by the outside, effectively improves the data acquisition rate and accuracy of the wind profiler radar, further plays the performance of the wind profiler radar and can be widely applied to wind profiler radar data processing software systems in a convection layer and a boundary layer.

Description

technical field [0001] The invention relates to a meteorological data analysis and processing technology, in particular to a method for obtaining a three-dimensional wind field with high accuracy after a series of processing using data obtained by wind profile radar, specifically a method for using wind profile radar Method for obtaining 3D wind field. Background technique [0002] As we all know, wind profiler radar is a pulse Doppler radar with vertical pointing and clear sky detection, which can detect the three-dimensional wind field in the atmosphere in real time. The main target of the radar is the clear-air atmospheric turbulence, and the Bragg scattering principle is used to detect the atmospheric refractive index index structure parameter C in the turbulence drifting with the wind n 2 , and then derive the true situation of the wind direction and speed in the atmosphere. Atmospheric refractivity depends on changes in factors such as temperature, humidity, and ai...
