Abstract

The invention provides a weather radar image processing method and a weather radar image processing system. The method includes receiving echo images of a weather radar, inputting the echo images intoa full-convolution neural network, classifying pixel points of the echo images, and acquiring predicated images of the pixel points marked with true echoes, wherein the full-convolution neural network comprises a deconvolution layer and a softmax layer. The method has the advantages that through the full-convolution neural network, the echo images of the weather radar are classified and marked, so that the true echoes and clutters in the echo images of the weather radar can be recognized effectively, and processing efficiency and recognition accuracy of weather radar images are improved.

Description

technical field [0001] The present invention relates to the field of image processing, and more specifically, to a weather radar image processing method and system. Background technique [0002] Doppler weather radar has an important impact on precipitation monitoring and forecasting, and its radar echo intensity can directly reflect the intensity of precipitation. Therefore, the data accuracy of Doppler weather radar is very important. Due to the limitation of its principle, the existing Doppler weather radar is easily affected by ground debris and birds at small elevation angles, resulting in a large amount of non-precipitation clutter. When the refractive index of the surface atmosphere decreases rapidly with the increase of altitude, the electromagnetic wave of low-elevation radar is refracted and propagates towards the ground instead, which will generate a large amount of super-refracted clutter. In addition, due to the influence of various electromagnetic noises in t...
