A Data Processing Method for Wind Profiler Radar

Abstract

The invention discloses a data processing method for wind profile radar, comprising: processing the power spectrum data of each height layer in each direction with a multi-peak spectrum algorithm and a single-peak spectrum algorithm; Judging the symmetry of the spectral peaks obtained under the multi-peak spectrum algorithm and the single-peak spectrum algorithm for the same height layer in the north-south direction; The height continuity of the spectral peaks obtained under the algorithm is judged; respectively judge whether the spectral peaks obtained under the multi-peak spectral algorithm and the single-peak spectral algorithm are credible spectral peaks for each height layer in each direction; The credible spectral peaks obtained under the multi-peak spectral algorithm at the same altitude replace the unreliable spectral peaks obtained under the single-peak spectral algorithm. The invention effectively fills the gap existing in the single-peak spectrum algorithm, thereby improving the detection accuracy 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 profiler radar. Background technique [0002] Wind profiler radar is a remote sensing device that detects high-altitude wind fields by emitting electromagnetic beams in different directions to the upper air, and receiving and processing the echo signals returned by these electromagnetic beams due to the uneven vertical structure of the atmosphere. Wind profiler radar can detect the change of meteorological elements such as wind direction and wind speed with altitude by using the Doppler effect, and has the advantages of high spatial and temporal resolution and high degree of automation. Wind profiler radar can enable ship controllers to accurately grasp low-altitude weather information, but due to the influence of low-altitude clutter, the real target is easily covered. Therefore, wind profiler radar needs to provide higher detectio...

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.
