Interferometric synthetic aperture radar (InSAR or IfSAR), is a geodetic technique uses two or more single look complex synthetic aperture radar (SAR) images to produce maps of surface deformation or digital elevation. It has applications as well, for monitoring of geophysical natural hazards, for instance earthquakes, volcanoes and landslides, also in engineering, in particular recording of su...

The need for widespread structural safety checks represents a stimulus the research of advanced techniques monitoring at scale single constructions or wide areas. In this work, strategy to preliminarily identify and rank possible critical in built environment is presented, based on joint exploitation satellite radar remote sensing measurements artificial intelligence (AI) techniques. are repres...

Subsidence is a natural hazard that affects wide areas in the world causing important economic costs annually. This phenomenon has occurred in the metropolitan area of Murcia City (SE Spain) as a result of groundwater overexploitation. In this work aquifer system subsidence is investigated using an advanced differential SAR interferometry remote sensing technique (A-DInSAR) called Stable Point ...

Australia is one of the world’s leading mineral resource extraction and exporting nations. Underground mining can cause ground surface displacement, which may in turn have serious impacts on the environment or man-built facilities. This paper describes the results of a study into the feasibility of surface subsidence (caused by underground coal mining) monitoring using differential interferomet...

On October 29, 2008, magnitude 6.4 earthquake occurred in a area of western Pakistan. One of the Japanese earth observation satellite, Advanced Land Observing Satellite (ALOS), observed this area by all onboard sensors, AVNIR-2, PRISM, and PALSAR. By optical imagery, AVNIR-2 and PRISM imagery, huge landslide (rock slide) and landslide dam were confirmed by visual interpretation. And also this l...

In conventional differential radar interferometry (DInSAR), the ground surface displacement can be measured along the line-ofsight. In order to measure the vertical and horizontal displacements DInSAR results of the same deformation derived from at least two different look directions are required. This study utilised the DInSAR results generated from ENVISAT data acquired from three different l...

In today’s urbanizing world, home of 28 megacities, there is a growing need for tools to assess urban policies and support the design and implementation of effective development strategies. Unsustainable practices of urbanization bring major implications for land and environment, and cause a dramatic increase of urban vulnerability to natural hazards. In Istanbul megacity, disaster risk reducti...

In this paper, the application of polarimetric optimization techniques for Differential SAR Interferometry (DInSAR) applications is studied. The objective of the proposed techniques is to increase the number of temporal coherent scatterers, improving thus the robustness of the DInSAR algorithms exploiting the polarimetric capabilities of data. The relationship between optimum coherences or ampl...
