Geohazard area

All types of geohazards can have significant socio-economic impacts. Monitoring geohazards using InSAR technology improves quantitative estimates of the extent and variability of specific hazards, enabling geotechnical engineers to quickly minimize the risk of damage. The following geohazards can be monitored: subsidence cavities, landslides, slope stability, debris flows, volcanoes, and seismic impact assessment.

Monitoring of hydraulic engineering facilities

Radar satellite InSAR is very suitable for monitoring water conservancy and hydropower projects near dam slopes, dams, watershed slope deformation hazards early identification, regular inspection, history tracing, dynamic tracking, water conservancy and hydropower infrastructure to achieve millimeter-level high-precision deformation information extraction, watershed slope hazards early identification of the "one map" drawing, auxiliary water conservancy and hydropower It can assist water conservancy and hydropower engineering experts in planning and design, operation and maintenance, disaster management, and decision-making support for emergency response and disaster reduction.

Infrastructure monitoring

In recent years, the launch of multi-resolution, multi-frequency SAR satellites has promoted the development of satellite monitoring technology for infrastructure health, and advances in InSAR technology have improved the refinement and precision of monitoring, making it possible to use satellites to give a "physical examination" of the entire city from space. Urban infrastructure health refers to the settlement and deformation of urban ground facilities. Our company is committed to the technical development and application of InSAR technology in urban infrastructure health monitoring.

Road transportation industry

Through the synthetic aperture radar interferometry (InSAR technology can obtain a wide range, high spatial and temporal resolution, long time series of transportation facilities and the surrounding area of the deformation details of the information, the monitoring accuracy can reach the millimeter level. It does not need to do on-site monitoring network construction, which is relatively fast and inexpensive compared with other traditional manual methods, and helps to reveal the deformation of transportation infrastructure and the development trend of ground settlement in the surrounding area.

Power sector monitoring

Using DInSAR, PSInSAR, JSInSAR and other all-day, all-weather high-precision wide-area surface deformation monitoring technology, can efficiently and comprehensively monitor the deformation distribution of substations, pylons, transmission corridors and other power facilities in the region, derived from the PSInSAR data of the discrete permanent scattering point characteristics.

Mine monitoring

Synthetic aperture radar interferometry (InSAR) is a new and promising remote sensing technology under development, and its interferometric mode can be applied to the monitoring of surface deformation over a wide area with outstanding features such as high accuracy and high spatial resolution, which can complement the observation technology based on point features with high temporal resolution.

Project Cases

InSAR survey of geologic hazards upstream of Luladi hydropower station

Rudira Hydropower Station is located in the southwest high mountain valley, which is a high susceptibility area for geologic disasters. The loose geology coupled with sudden heavy rainfall often triggers mudslide disasters, which directly threaten the safety of Rudiradi Hydropower Station.
Through the InSAR technology, a year-long data analysis of the topography of the upstream area of Luladi Hydropower Station was carried out, and it was found that obvious subsidence existed in the vicinity of Lower Eagle's Nest, West Sheep Circle House, Niu Shui Tang and Horse Leech, with a total area of more than 14,000 square meters. Through InSAR technology, the risk of geological disasters in the upstream of Luladi Hydropower Station was discovered in time, which provided solid technical support for the safety of Luladi Hydropower Station.

InSAR Census of Road Settlement in Xining City, China

Xining highway is mostly wet trapping loess roadbed, and years of water seepage will lead to loss of roadbed material and gradually form underground sinkholes. Under the repeated action of regular load, it will make the original design capacity of the roadbed fail and the bearing capacity decline, which will easily lead to road subsidence or even collapse in the long run.
In order to comprehensively understand the road deformation condition in Xining City, using the technology of SBAS-InSAR, it took one week to complete the 74 scenes of sentinel-1A data processing from January 3, 2018 to July 2, 2021, to get the census results of road settlement in Xining City, and to successfully identify some of the urban roads that have hidden dangers. According to the SBAS-InSAR monitoring results, it provides data basis for road safety management in Xining.

InSAR Census of Geologic Hazards in Xining City

Xining City is a typical city of mountainous valleys, with a fragile geological environment, and the largest geological disaster is characterized by landslides and frequent landslides, which greatly jeopardize the city's public safety.
In order to comprehensively assess the impact of geohazards in Xining City, a city-wide geohazard survey was completed in one month using InSAR technology. Major geohazardous terrain identification and screening was conducted in the urban area of Xining City around the mountain area, including the Beishan Market, near Xixing Garden, Xining Nanshan, Xining Railway Station, along the Beijing-Tibet Railway, near the Xiehe Expressway and near Xiejiazhai Village. According to the insar census results, Xining City has a number of large areas with excessive deformation and the existence of landslides and other geologic hazards, which timely discovered the danger of geologic hazards in Xining City, and provided a solid technical guarantee for the city's public safety.
