Retrieving 3-D Large Displacements of Mining Areas from a Single Amplitude Pair of SAR Using Offset Tracking
Due to the side-looking imaging geometry of the current synthetic aperture radar (SAR) sensors, only ground deformation along the radar’s line-of-sight (LOS) and azimuth directions can be potentially obtained from a single amplitude pair (SAP) of SAR using offset tracking (OT) procedures. This significantly hinders the accurate assessment of mining-related hazards and better understanding of th...
متن کاملRetrieving three-dimensional coseismic displacements of the 2008 Gaize, Tibet earthquake from multi-path interferometric phase analysis
In this paper, synthetic aperture radar (SAR) data from ENVISAT ASAR ascending, descending and ALOS PALSAR ascending orbits are collected to investigate the coseismic displacements of the Mw 6.4 earthquake occurred in Gaize, Tibet on January 9, 2008 and the Mw 5.9 aftershock on January 16, 2008. Two interferometric phase analysis techniques, i.e., D-InSAR and multi-aperture InSAR, are employed ...
متن کاملThree-Dimensional Image of A Communicating Uterus
Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).
متن کاملLocal interpolation of coseismic displacements measured by InSAR
Coseismic displacements play a significant role in characterizing earthquake causative faults and understanding earthquake dynamics. They are typically measured from InSAR using preand post-earthquake images. The displacement map produced by InSAR may contain missing coseismic values due to the decorrelation of ASAR images. This study focused on interpolating missing values in the coseismic dis...
متن کاملThree Dimensional Image Reconstruction from Fourier Magnitude Measurements
The problem of recovering a three-dimensional image from samples of the Fourier magnitude and a priori knowledge of the object structure is addressed. It is shown that this mathematical problem relates to a method for remotely imaging opaque surfaces. Two broad approaches to finding an iterative solution are presented. One manipulates the support of the autocorrelation function, which can be es...
