Foliage penetration effect on polarimetric SAR interferometry observation of forest [PDF]

, 2008
The capability of electromagnetic waves to penetrate trough foliage (FOLPEN), combined with the potentialities of the polarimetric SAR interferometry (POL-InSAR) are demonstrated to be valid instruments for the investigation of forest characteristics and

Seismic attenuation in Faroe Islands basalts [PDF]

We analysed vertical seismic profiling (VSP) data from two boreholes at Glyvursnes and Vestmanna on the island of Streymoy, Faroe Islands, to determine the magnitude and causes of seismic attenuation in sequences of basalt flows.

Nondestructive testing of railway embankments by measuring multi-modal dispersion of surface waves induced by high-speed trains with linear geophone arrays

Seismica
To effectively address engineering challenges and risks, it is crucial to characterize mechanical properties of near-surface environments. The Multichannel Analysis of Surface Waves (MASW) has proven to be a valuable active seismic imaging technique by ...

Deghosting, Demultiple, and Deblurring in Controlled-Source Seismic Interferometry

International Journal of Geophysics, 2011
With controlled-source seismic interferometry we aim to redatum sources to downhole receiver locations without requiring a velocity model. Interferometry is generally based on a source integral over cross-correlation (CC) pairs of full, perturbed (time ...

Imaging ore-controlling structures in the Western Qinling Orogen through integrated interpretation of passive surface and reflected waves

Results in Engineering
Imaging subsurface structures in mining areas is essential for safe extraction, subsidence monitoring, and potential ore-bearing zones. In a gold mine within the Western Qinling orogen, high-resolution imaging of the subsurface was required to guide ...
