Short summary
We introduce an AI-based approach to identify unwanted signals in weather radar images using a neural network. To address the challenge of acquiring sufficient amounts of labeled radar images, the network is trained on synthetically generated radar images. By evaluating the segmentation performance of the trained network on experimentally measured radar images with expert-labeled ground truth, we demonstrate that it outperforms a state-of-the-art method currently used at Deutscher Wetterdienst.
