Embodiment Construction
[0058] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, and the described specific embodiments are only for explaining the present invention, and are not intended to limit the present invention.
[0059] The present invention provides a strong convergence field identification and speed correction method based on Doppler weather radar data. The design idea is: design a new coordinate system to convert radially distributed radar data into grid point data, and at the same time complete high reflection area extraction; design a detection template, and obtain a parameter vector describing the convergence strength and position of the convergence point on the basis of quickly locating the convergence point; propose to generate a convergence zone from the convergence point, and then use the trend of the convergence zone to correct the convergence intensity The idea and algor...
