Abstract

Synthetic Aperture Radar (SAR) has emerged as a pivotal technology in geosciences, offering unparalleled insights into Earth's surface. Indeed, its ability to provide high-resolution, all-weather, and day-night imaging has revolutionized our understanding of various geophysical processes. Recent advancements in SAR technology, that is, developing new satellite missions, enhancing signal processing techniques, and integrating machine learning algorithms, have significantly broadened the scope and depth of geosciences. Therefore, it is essential to summarize SAR's comprehensive applications for geosciences, especially emphasizing recent advancements in SAR technologies and applications. Moreover, current SAR-related review papers have primarily focused on SAR technology or SAR imaging and data processing techniques. Hence, a review that integrates SAR technology with geophysical features is needed to highlight the significance of SAR in addressing challenges in geosciences, as well as to explore SAR's potential in solving complex geoscience problems. Spurred by these requirements, this review comprehensively and in-depth reviews SAR applications for geosciences, broadly including various aspects in air-sea dynamics, oceanography, geography, disaster and hazard monitoring, climate change, and geosciences data fusion. For each applied field, the scientific advancements produced because of SAR are demonstrated by combining the SAR techniques with characteristics of geophysical phenomena and processes. Further outlooks are also explored, such as integrating SAR data with other geophysical data and conducting interdisciplinary research to offer comprehensive insights into geosciences. With the support of deep learning, this synergy will enhance the capability to model, simulate, and forecast geophysical phenomena with greater accuracy and reliability.

用于地球科学的合成孔径雷达
合成孔径雷达(SAR)已成为地球科学领域的一项关键技术,可提供对地球表面无与伦比的洞察力。事实上,合成孔径雷达提供高分辨率、全天候和昼夜成像的能力彻底改变了我们对各种地球物理过程的认识。合成孔径雷达技术的最新进展,即开发新的卫星任务、增强信号处理技术和整合机器学习算法,大大拓宽了地球科学的广度和深度。因此,有必要总结合成孔径雷达在地球科学领域的综合应用,特别是强调合成孔径雷达技术和应用的最新进展。此外,目前与合成孔径雷达相关的综述论文主要侧重于合成孔径雷达技术或合成孔径雷达成像和数据处理技术。因此,需要一篇将合成孔径雷达技术与地球物理特征相结合的综述,以突出合成孔径雷达在应对地球科学挑战方面的重要意义,并探索合成孔径雷达在解决复杂地球科学问题方面的潜力。在这些要求的推动下,本综述全面深入地回顾了合成孔径雷达在地球科学领域的应用,广泛包括海气动力学、海洋学、地理学、灾害和危险监测、气候变化以及地球科学数据融合等各个方面。在每个应用领域,通过将合成孔径雷达技术与地球物理现象和过程的特征相结合,展示了合成孔径雷达带来的科学进步。此外,还探讨了进一步的展望,例如将合成孔径雷达数据与其他地球物理数据进行整合,以及开展跨学科研究以提供对地球科学的全面见解。在深度学习的支持下,这种协同作用将增强对地球物理现象进行建模、模拟和预测的能力,并提高其准确性和可靠性。
