收藏资源简介：
数据主编：毕辉 高维星载合成孔径雷达（Synthetic Aperture Radar, 简称SAR）成像在城市测绘和灾害监测等各个领域具有重要意义，三维结果提供了被观测场景的空间散射结构信息，四维结果提供了被观测场景的精细形变信息。面对城市环境的日益复杂性以及对精确和详细的空间数据的需求日益增长，使得先进的高维成像技术发挥愈为重要的作用。目前，尽管干涉、层析SAR在内的三维SAR成像技术的发展日益成熟，但在实际应用中仍面临星载数据处理复杂度高、分辨率低以及数据获取周期长的挑战。提供高质量的SAR三维成像数据集，不仅能够填补现有研究中的空白，还将推动SAR成像技术的进一步发展，支持智慧城市建设，并扩大其在例如人工智能等各领域的应用。本数据集基于具有干涉能力的C波段商业SAR卫星——涪城一号构建了北京首都国际机场的数据集，概述了北京首都国际机场数据集的构建与规划，给出了数据集的文件及其他具体信息，说明了制作该数据集的具体方法，为后续的科学研究提供数据支持。 数据使用说明请见涪城一号SAR三维成像数据集1.0 介绍.pdf
Data Editor: Bi Hui. High-dimensional spaceborne Synthetic Aperture Radar (SAR) imaging is of great significance in various fields such as urban surveying and mapping and disaster monitoring. 3D results provide spatial scattering structure information of the observed scene, while 4D results provide fine deformation information of the observed scene. Facing the increasing complexity of urban environments and the growing demand for accurate and detailed spatial data, advanced high-dimensional imaging technologies play an increasingly important role. Currently, although 3D SAR imaging technologies including interferometric SAR and tomographic SAR have become increasingly mature, they still face challenges in practical applications such as high complexity of spaceborne data processing, low resolution, and long data acquisition cycle. Providing high-quality 3D SAR imaging datasets can not only fill the gaps in existing research, but also promote the further development of SAR imaging technology, support the construction of smart cities, and expand its applications in various fields such as artificial intelligence. This dataset is constructed for Beijing Capital International Airport based on "Fucheng No.1", a C-band commercial SAR satellite with interferometric capability. It outlines the construction and planning of the Beijing Capital International Airport dataset, provides detailed information about the dataset files and other specifics, explains the specific methods for creating the dataset, and provides data support for subsequent scientific research. Please refer to "Fucheng No.1 SAR 3D Imaging Dataset 1.0 Introduction.pdf" for data usage instructions.
