ABOUT InSAR

Interferometric Synthetic Aperture Radar (InSAR) is a powerful technique for the estimation of multi-temporal surface deformation processes, allowing a detailed monitoring of ground and structures through the use of sensors installed on satellite (A-DInSAR) and terrestrial (TInSAR) platforms.

One of the greatest value and peculiarity of Satellite InSAR technology is the capability to perform historical displacement analysis, thanks to the archives of imagery available since 1992. Furthermore, thanks to the new generation of satellites and their acquisition programs, it is nowadays possible to perform detailed analysis for monitoring purposes.

InSAR VISUALIZATION TOOL

The InSAR Visualization Tool is our web based platform for the monitoring data distribution which allows to explore the interferometric products and analyse each measurement point, observing the time series of displacement.

The platform supports different kind of monitoring data, acquired with different types of monitoring systems, offering the opportunity to manage complex projects thanks also to its customizable and user friendly interface.

INSarPECT APP

INSarPECT supports the field surveys as you can combine and superimpose satellite InSAR data with your collected field data, simply through your mobile devices. Your field teams can then collect records including geo-referred information such as text, photos, videos, vocal notes, and more.

This ensure that any inspection report is linked exactly to the location where issues were found. No more pen and paper needed. Everything will be recorded as is and synchronized with the server and all other linked mobile devices. INSarPECT also assures that InSAR results are used to their maximum potential, closing the loop between satellite and field work.

The added value provided by PS ToolBox consists in the effective mapping and understanding the detected deformation processes, in assessing the health and the potential risk of structures and infrastructures, also for predictive maintenance purposes.

PS ToolBox

PS ToolBox is the new GIS plugin for the post-processing of InSAR data conceived and developed by NHAZCA S.r.l.
The plugin includes a series of tools for the spatialization, integration and interactive analysis of PSI data such as:

  • HeatMap;
  • KMZ export;
  • Filtering;
  • Interferometric Sections;
  • Linear infrastructures – interference analysis;
  • Vectorial decomposition – from ascending and descending orbits datasets;
  • PS Time Series – optimized visualization tool;
  • Trend Change Detection – analysis of time series of displacement.

TRIVIA – Terrestrial Radar Interferometry VIsualization and Analysis

TRIVIA software is the result of more than 10 years long experience in Terrestrial SAR Interferometry gained in the frame of tenths of projects on landslides, dams, rock-slopes, bridges, buildings etc.

The software is able to perform advanced analyses of Terrestrial SAR images, processing data from several radar manufacturers like IDS GeoRadar, MetaSensing and Echoes. By using TRIVIA, NHAZCA is able to support clients with excellent real-time data processing capabilities.

QUIB – Quick Installation Basement

The QUIB is an easy to transport modular basement designed and realized by NHAZCA for the quick installation (about 2 hours) of a terrestrial interferometric monitoring platform. Once installed, the size of the system is 280×60×200 cm.

Moreover, the QUIB can be installed on every kind of ground thanks to its eight adjustable legs. It can be completely enclosed by polycarbonate or wood panels for the equipment safety. Thanks to the QUIB, NHAZCA can perform the installation of monitoring platform in less than 24 hours from the call in emergency conditions. Furthermore, the rigorous design technical solutions comply with the requirements of prompt intervention protocols developed by NHAZCA for civil protection purposes.

RAPS – Remote Area Power Supply

RAPS is a stand-alone power supply system, consisting of a modular photovoltaic system, storage batteries that accumulate the surplus energy produced during sunny hours to make it available at various times and a backup electric generator, allowing the continuous power supply even in case of emergency.

RAPS is thus able to produce electricity to supply the TInSAR system, even in remote areas. Thanks to an energy box, built ad-hoc for the management of the system, it is possible to monitor – continuously and remotely – the status of the equipment and the total charge of the system.

Corner Reflectors

As part of the monitoring services, NHAZCA offers the supply and installation of artificial reflectors (corner reflectors) of new concept, which can also be used for satellite InSAR analysis. The corner reflectors are passive targets designed to obtain a backscattered signal stable in time, allowing to obtain accurate displacement measurements.

These are metallic devices that do not require any power supply and/or maintenance after installation. Because of their own characteristics (material, shape and size), they allow to obtain monitoring points in strategic areas and to return accurate time series of displacement, especially in regions characterized by lack or scarcity of natural reflectors.

SUCCESSFUL APPLICATIONS

TRAINING

NHAZCA promotes, also in collaboration with professional organizations and associations in Italy and abroad, highly professional training courses, focused on geotechnical and structural monitoring, remote sensing applications and support to land use planning and design.

The courses, designed to provide skills and updates in line with continuous technological and cultural developments, have already seen the participation in the last 12 years of more than 700 professionals from over 50 countries with the involvement of over 60 companies.

9TH ICGSM

02 – 06 May 2023, Rome

The ninth Edition of the International Course on Geotechnical and Structural Monitoring will feature this year a large Expo Area to showcase the newest instrumentation, and run real demos.

Several thematic Courses & Workshops will be organized by leading scientists in the field to stimulate exchange of the latest scientific and technological knowledge and offer training and updating in new techniques.
