- W4387623975 abstract "This paper presents clutter detection and mitigation for polarimetric phased array weather radar measurements using machine learning. Three approaches of naive Bayes classifier (NBC), multilayer perceptron (MLP), and convolutional neural network (CNN) are used for clutter detection in the cylindrical polarimetric phased array radar measurements. Results show that CNN achieves the best performance in clutter detection, followed by MLP and NBC. This is because CNN utilizes spatial information of the input images, which has different features for clutter from that for weather. It is also shown that the combination of physics-based discriminants of power ratio and raw radar measurements is more effective in clutter detection than the direct use of raw radar measurements. In addition, CNN is employed for clutter mitigation and its performance is compared with the traditional speckle filter technique. It is demonstrated that CNN outperforms the speckle filter and incorporation of power ratio in the training process could further improve CNN’s performance in clutter mitigation." @default.
