【簡介】 This book delivers a comprehensive introduction to the principles and applications of synthetic aperture radar (SAR) for measuring and monitoring surface motion caused by a wide range of geophysical phenomena, such as earthquakes, volcanoes, urban subsidence, and landslides. Along with covering essential SAR concepts like the radar equation, resolution, and signal processing techniques such as focusing and interferometry, the book provides an in-depth exploration of advanced methodologies, including PSInSAR, STUN, PSP, StaMPS, SBAS, QPS, and SqueeSAR, all critical for tracking long-term surface deformation.Techniques such as pixel offset tracking and SAR-based absolute positioning are also thoroughly introduced, with illustrative examples provided to enhance understanding. Each step of these techniques is clearly explained, breaking down complex topics for readers. Additionally, a vivid case study on ship detection illustrates SAR imaging principles and targets scattering characteristics, offering a strong foundation for SAR-based measurement techniques.Written in an accessible and clear style, the book features numerous real-world examples and case studies drawn from modern SAR missions like Sentinel-1 and TerraSAR-X, effectively bridging the gap between theoretical foundations and practical applications. This valuable reference is ideal for graduate students, researchers, and professionals in the fields of remote sensing, geodesy, geosciences, and engineering, providing not only essential foundational knowledge but also insights into the latest technological advancements in surface motion monitoring.
