基于深度学习算法的极化合成孔径雷达通用分类器设计
General Purpose PolSAR Classifier Based on Deep Learning Algorithm
摘要
Abstract
Terrain classification is one of the most important applications of polarimetric synthetic aperture radar (PolSAR)data. The classic algorithms are limited by manual designed features and classifiers. However, deep learning can extract hierarchical features from big data. Open literatures of deep-learning based PolSAR data classification approaches are firstly reviewed, and one general purpose PolSAR image classifier is then presented based on deep learning and PolSAR big data. Manually labelled data are used for training, and experiments are carried out on both airborne and space-borne SAR data with variant resolution. The results show that the proposed classifier is highly accurate and efficient, which is helpful for big data utilization, especially for GF-3PolSAR data.关键词
