Southern California, USA, has been suffering severe surface deformation due to its active crustal movement under the north–south compression of Pacific Plate and North American Plate. Meanwhile, affected by groundwater extraction recharge, oil exploitation, subsidence, uplift, seasonal occur commonly in this region. In paper, multi-path SAR datasets were collected investigate monitor California...

Landslide monitoring is important for geological disaster prevention, where Synthetic Aperture Radar (SAR) images have been widely used. Compared with the Interferometric SAR (InSAR) technique, intensity-based offset tracking methods (e.g., Normalized Cross-Correlation method) can overcome the limitation of InSAR’s maximum detectable displacement. The normalized cross-correlation (NCC) method, ...

How to accurately determine the mechanical parameters of rockfill is one of the key issues of concrete-face rockfill dams. Parameter back-analysis using internal or external monitoring data has been proven to be an efficient way to solve this problem. However, traditional internal or external monitoring methods have limitations in efficiency and long-term monitoring. In this paper, the displace...

Synthetic aperture radar (SAR) is a coherent active microwave imaging method. In remote sensing it is used for mapping the scattering properties of the Earth’s surface in the respective wavelength domain. Many physical and geometric parameters of the imaged scene contribute to the grey value of a SAR image pixel. Scene inversion suffers from this high ambiguity and requires SAR data taken at di...

Interferometric Synthetic Aperture Radar (InSAR) technology has been widely used in various applications. The registration of SAR (Synthetic Aperture Radar) images is the first step in interferometric processing therefore accurate registration is essential for the successful creation and interpretation of interferometric products. However, with the growing number of SAR satellite launch and the...

Highly variable weather conditions, especially the rapidly changing water vapor distribution, bias the interpretation of interferometric synthetic aperture radar (InSAR) images. Any change of atmospheric condition is reflected as differential propagation delay in the InSAR images, which is difficult to distinguish from the real ground motion. Moreover, for areas which cover a wide range of alti...
