Mountain Landslide Monitoring Using a DS-InSAR Method Incorporating a Spatio-Temporal Atmospheric Phase Screen Correction Model

Remote Sensing
The detection of potential rural mountain landslide displacements using time-series interferometric Synthetic Aperture Radar has been challenged by both atmospheric phase screens and decoherence noise. In this study, we propose the use of a combined distributed scatterer (DS) and the Prophet_ZTD-NEF model to rapidly map the landslide surface ...

Dual Pol-InSAR Forest Height Estimation By Means Of TANDEM-X Data

, 2012
The TanDEM-X mission [1] provides for the first time single pass (single- and dual-) polarimetric interferometric data from space. This allows the acquisition and analysis of Pol-InSAR data without the disturbing effect of temporal decorrelation on a ...

Performance Comparison of FH/MC DS-CDMA with Single- and Multi-Carrier DS-CDMA

, 2000
In this contribution we review the slow frequency hopping multicarrier direct-sequence code-division multiple-access (SFH/MC DS-CDMA). Then, the system's performance is ecalated and compared to that of the conventional single-carrier (SC) DS-CDMA and MC ...

Shortcomings of InSAR for studying megathrust earthquakes: The case of the M w 9.0 Tohoku-Oki earthquake

, 2012
Interferometric Synthetic Aperture Radar (InSAR) observations are sometimes the only geodetic data of large subduction-zone earthquakes. However, these data usually suffer from spatially long-wavelength orbital and atmospheric errors that can be ...
