Journal ArticleDOI
Surface and borehole ground-penetrating-radar developments
TL;DR: The specific aspects of borehole radar are discussed and recent developments to become more sensitive to orientation and to exploit the supplementary information in different components in polarimetric uses of radar data are described.
Journal ArticleDOI
General Polarimetric Model-Based Decomposition for Coherency Matrix
TL;DR: Double- and odd-bounce scattering models were generalized to fit the cross-polarization and off-diagonal terms, by separating their independent orientation angles, and a general decomposition framework is proposed that utilizes all elements of a coherency matrix.
Journal ArticleDOI
Modeling and Interpretation of Scattering Mechanisms in Polarimetric Synthetic Aperture Radar: Advances and perspectives
TL;DR: Recent advances in scattering modeling and model-based decomposition theorem were reviewed and notable achievements include orientation compensation processing, nonnegative eigenvalue constraint, generalized scattering models, complete information utilization, full-parameter inversion strategy, and the polarimetric-interferometric decomposition scheme.
Journal ArticleDOI
Tsunami Damage Investigation of Built-Up Areas Using Multitemporal Spaceborne Full Polarimetric SAR Images
Si-Wei Chen,Motoyuki Sato +1 more
TL;DR: Experimental results from after- and before-tsunami comparisons validate the efficiency of these indexes, since the built-up areas with different damage levels can be well discriminated and demonstrate the importance of full polarimetric information for natural disaster assessment.
Journal ArticleDOI
Pre-stack migration applied to GPR for landmine detection
TL;DR: In this article, a step-frequency continuous-wave array antenna ground penetrating radar system, called SAR-GPR, was developed to acquire common middle point multi-offset data.
