Advanced Imaging Radar for environmental Monitoring

 

Synthetic Aperture Radar - SAR

We offer a variety of remote sensing solutions for timely monitoring of earth movements and man-made structures. The core technology employed here is the Synthetic Aperture Radar (or SAR), which is a high-resolution 2D radar. The applications include landslide monitoring, terrain subsidence monitoring, road surface profiling, as well as structural health monitoring of bridges, dams, high-rise buildings, and transmission towers.

 
 

Remote Sensing Services

We provide a complete, end-to-end remote sensing solution and consultancy services for landslide monitoring, structural health inspection, environmental impact assessment and more.

Case Study 1 : GBSAR for Landslide Monitoring

Geo-hazards due to ground movements such as landslides and terrain subsidence can lead to considerable human and economic losses. Early detection of landslide symptoms is very crucial for risk assessment and hazard management. We provide a full range of sensing solution that can perform continuous monitoring of a wide area under all weather conditions. The authority can now react more quickly and more precisely than they can using other conventional methods.

Benefits of using GBSAR for Landslide Monitoring:

Soil Errosion.jpg
  • Greater Precision : GBSAR can provide high resolution (sub-mm) change detection at remote distance of more than 1 km.
  • Timely and All Weather Monitoring : GBSAR can provide real-time monitoring of landslide-prone areas under all weather conditions.
  • Safer : GBSAR can operate 24/7 autonomously and remotely, without putting any personnel at risk.
  • Wider Area of Coverage : Traditional ground-truth measurement methods can only cover several discrete points within the area of interest. Now, the entire area can be monitored using GBSAR.
  • Earlier Detection : By comparing the temporal changes of the data, subtle ground movements can be detected at earlier stage. Preventive actions can be carried out to minimize the risk of landslides and lost of lives.

Depending on your mission objective, we can configure our sensing system to suit your specific requirements. High resolution 2D imagery that are essential for risk assessment and landslide study can readily be acquired. It is an efficient way to provide continuous monitoring of unstable hillside areas, construction sites, and open-pit mines.


Monitoring of Unstable Hillsides

Due to intense urban development, more and more buildings, roads and other facilities are developed in close proximity to steep hillsides. These hillside areas may be susceptible to landsliding during periods of high seasonal rainfall, which could be a serious hazard if not attended to. GBSAR can provide continuous monitoring of the hillsides as part of the landslide prevention and mitigation programme.


Monitoring of Construction Sites

With the growing demand for land to meet housing needs and other purposes, there is a trend to locate developments closer to areas of steep terrains with a consequent increase in landslide risk. We provide real-time monitoring on natural terrains and man-made slopes as part of the safety measures for the construction sites.


Monitoring of Open-Pit Mines

Mining is always threatened by slope instability and landslide hazards. Slope monitoring using GBSAR forms an important element of slope management on open-pit mines. It provides timely information for assessing the risk of the slop design and detecting unstable ground movements.


Case Study 2 : GBSAR for Structural Health Inspection

Structural Health Monitoring (SHM) is an important element for sustainable management of public infrastructures such as bridges, buildings, dams, roadways, and transmission towers. GBSAR can be applied in SHM system to detect the presence of damages or instabilities of any engineering structures, providing the essential information that help the authorities to accurately monitor the general health conditions of the infrastructures.

Benefits of GBSAR for Structural Health Inspection:

  • Greater Sensitivity : GBSAR can provide highly sensitive change detection in sub-mm range.
  • Timely and Frequent Monitoring : GBSAR can provide real-time and continuous monitoring of engineering structures.
  • All weather conditions : GBSAR can operate 24/7 autonomously and remotely, under all weather conditions.
  • Wider Area of Coverage : Traditional structural inspection methods can only cover several discrete points of the structure. Now, the entire structure can be monitored using GBSAR.
  • Earlier Detection : By comparing the temporal changes of the data, structural instability can be detected, identified and analyzed. Preventive actions can be carried out to minimize the risk of collapse.

Depending on your mission objective, we can configure our sensing system to suit your specific requirements. High resolution temporal data that are essential for structural health analysis and risk assessment can readily be acquired. It is an efficient way to provide continuous monitoring of structural stability of bridges, buildings, roads, dams, transmission towers and more.


Inspection of Bridges and Roadways

It is of great important for the nation to continuously monitor the conditions of public infrastructures such as bridges, highways and airport runways. We provide periodic inspection services on bridges and roadways as part of the safety measures for public infrastructures.


Inspection of Transmission Towers

Transmission towers are usually located at remote areas that are covered by hilly topography. Landslide is a major threat which may cause failure to the tower structure and subsequently affect the electricity supply. We provide a complete setup to remotely monitor the towers and slopes without putting any personnel at risk.


Inspection of Dams

Regular maintenance and thorough inspection must be carried throughout the lifetime of a dam. GBSAR is an effective remote sensing system that can provide early detection of deficiencies of the dam structure and prevention of failure.
