Embodiment Construction
[0089] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0090] Such as Figure 1 to Figure 4 As shown, the present invention proposes a multi-radar station bird situation information fusion and imaging method, which performs bird situation information fusion and imaging based on the radar observation data contained in the weather radar secondary data file.
[0091] The method of the present invention first obtains the secondary data files of multiple radar stations within a specific period of time and carries out the construction of the bird situation database and the initialization setting of the fusion image; The three-dimensional space information is associated with the fused image to generate a data pool array corresponding to each image unit in the fused image; finally, according to the latitude and longitude information of each image unit in the fused image and its corresponding data pool array, the statistical repre...

The invention provides a multi-radar-station bird situation information fusion and imaging method, and belongs to the field of radar target recognition and information fusion imaging. The method comprises the following steps: firstly, obtaining secondary data files of a plurality of radar stations in a specific time period, carrying out initialization setting on a bird situation fusion image, and then generating a data pool array corresponding to each image unit in the bird situation fusion image according to bird situation information and two-dimensional space information extracted by each radar station; and finally, drawing the bird condition fusion image according to the latitude and longitude information of each image unit in the bird condition fusion image and the corresponding data pool array. According to the invention, bird condition information extraction can be carried out based on the meteorological radar secondary data file, and effective fusion of bird conditions observed by multiple meteorological radar stations under different time scales is realized.
Description
technical field [0001] The invention belongs to the field of radar target recognition and information fusion imaging, and in particular relates to a multi-radar station bird situation information fusion and imaging method. Background technique [0002] The networked meteorological radar can not only accurately describe and track multi-category meteorological targets, but also provide more identifiable features of biological targets (birds, insects, bats). It provides very effective observation methods for the identification, tracking and activity law research of the system, and provides effective observation methods and reference information for agricultural and forestry disaster early warning, ecological environment monitoring and protection, aviation security threat assessment and other fields. Therefore, the relevant research based on the observation data in the weather radar secondary data file can provide strong data support for future research in technical fields such ...
