In this paper, land subsidence susceptibility was assessed for Shahryar County in Iran using the adaptive neuro-fuzzy inference system (ANFIS) machine learning algorithm. Another aim of present paper to assess if ensembles ANFIS with two meta-heuristic algorithms (imperialist competitive algorithm (ICA) and gray wolf optimization (GWO)) would yield a better prediction performance. A remote sens...

[1] Synthetic aperture radar (SAR) interferometry is a technique that provides high-resolution measurements of the ground displacement associated with many geophysical processes. Advanced techniques involving the simultaneous processing of multiple SAR acquisitions in time increase the number of locations where a deformation signal can be extracted and reduce associated error. Currently there a...

We have analyzed the far-field approximation of the Green’s function representation for seismic interferometry. By writing each of the Green’s functions involved in the correlation process as a superposition of a direct wave and a scattered wave, the Green’s function representation is rewritten as a superposition of four terms. When the scattered waves are modeled with the Born approximation, i...

Abstract Structural health monitoring (SHM) can support decision makers in structural integrity management by providing information about occurrence of damage and its evolution time. Recently, due to new Synthetic Aperture Radar (SAR) missions, remote sensing through active satellites provides a promising methodology capable infrastructure assets. This paper investigates the use Multi‐Temporal ...

Presently, ground subsidence in urban areas is becoming a peril to the infrastructure and society. In this study, we conducted detailed analysis of results, based on Persistent Scatterer Interferometry (PSI), Global Navigation Satellite System (GNSS) groundwater ‘World Heritage City’ Ahmedabad, major metro city western India. The PSI technique applied measure using Sentinel 1 A dataset for peri...
