InSAR Forensics: Tracing InSAR Scatterers in High Resolution Optical Image
نویسندگان
چکیده
The current synthetic aperture radar (SAR) theory makes a quite restrictive assumption – linearity – in the SAR imaging model, for the convenience of mathematical derivation. That is to say the imaged area is considered as an ensemble of individual point scatterers whose scattered fields and, hence, their responses in the SAR image superimpose linearly [1]. This is the so called the first Born approximation. However, the reality is, for sure, more complicated than such approximation.

Semantic Interpretation of Insar Point Cloud
The proposed approach consists of the following steps: 1. Retrieve the 3D positions of the scatterers from SAR images, i.e. a tomographic SAR inversion. 2. Co-register the 3D point cloud of the SAR scatterers with a reference 3D airborne LiDAR surface model, due to the relative position of the SAR point cloud to the reference point. 3. Co-register high resolution optical image with the referenc...
متن کاملCR-Based TerraSAR-X Interferometry for Landslide Monitoring
To monitor and detect the events of landslide, rock-fall along the banks of the Yangtze River in the Three Gorges area, the differential INSAR technique with corner reflectors (CR-Based INSAR) might be more effective than the conventional geological, and discrete GPS measurement techniques, conventional D-INSAR, as well as nature persistent scatterers method. Unfortunately, in most places of th...
متن کاملLayover Separation in Airborne Single Pass Multi-baseline InSAR Data Based on Compressive Sensing
The analysis of urban areas by means of very high resolution SAR remote sensing always has to deal with effects caused by the side-looking imaging geometry. Recently, the separation of scatterers that collapsed in one layover affected resolution cell has been thoroughly investigated for multi-baseline InSAR configurations. While most of the time repeat pass data acquired by satellite SAR system...
متن کاملPersistent Scatterer localization and prediction technique
Synthetic aperture radar (SAR) Persistent Scatterer Interferometry (PS-InSAR) is an extension of the Differential Interferometry (D-InSAR). Using a large data stack consisting of a time-series of SAR images of the same area, stable reflectors which persist over a long period of time, the so-called Persistent Scatterers (PS), are determined and the phase shifts of these PS over time are measured...
متن کاملUrban Building Detection from Optical and Insar Features Exploiting Context
We investigate the potential of combined features of aerial images and high-resolution interferometric SAR (InSAR) data for building detection in urban areas. It is shown that completeness and correctness may be increased if we integrate both InSAR double-bounce lines and 3D lines of stereo data in addition to building hints of a single optical orthophoto. In order to exploit context informatio...
