Data processing method for wind profile radar

Abstract

The invention discloses a data processing method for a wind profile radar. The data processing method comprises the steps of: respectively processing power spectrum data of each height layer in each direction by adopting a multi-peak spectrum algorithm and a single-peak spectrum algorithm; performing symmetry judgment on spectral peaks of the same height layer in the east-west direction and the south-north direction under the multi-peak spectrum algorithm and the single-peak spectrum algorithm respectively; respectively carrying out high continuity judgment on spectral peaks of each height layer in each direction under the multi-peak spectrum algorithm and the single-peak spectrum algorithm; respectively judging whether the spectral peaks of each height layer in each direction obtained under the multi-peak spectrum algorithm and the single-peak spectrum algorithm are credible spectral peaks or not; and replacing the incredible spectrum peaks obtained under the single-peak spectrum algorithm with credible spectrum peaks of the same height layer in the same direction obtained under the multi-peak spectrum algorithm. The data processing method effectively fills the void existing in the single-peak spectrum algorithm, thereby improving the detection accuracy rate of low-altitude wind.

Description

technical field [0001] The invention relates to the technical field of radar data processing, in particular to a data processing method for wind profile radar. Background technique [0002] Wind profiler radar is a remote sensing device for high-altitude wind field detection by transmitting electromagnetic beams in different directions to the high altitude, receiving and processing the echo signals returned by these electromagnetic beams due to the uneven vertical structure of the atmosphere. Using the Doppler effect, the wind profiler radar can detect the changes of meteorological elements such as wind direction and wind speed over it with altitude, and has the advantages of high spatial and temporal resolution and high degree of automation. Wind profiler radar can enable ship control personnel to accurately grasp low-altitude weather information, but due to the influence of low-altitude clutter, real targets are easily covered. Therefore, wind profiler radar needs to provi...

AI Technical Summary

Problems solved by technology

The wind profile radar can enable the control personnel on board to accurately grasp the low-altitude weather information, but due to the influence of low-altitude clutter, the real target is easy to be covered, so the wind profile radar needs to provide higher detection accuracy

[0003] The data processing method used for wind profile radar in the prior art is mainly a single-peak spectrum algorithm. There are false targets in the processing results, and a small part of the profile will have holes, resulting in low low-altitude wind detection ability and inaccurate detection.
