Ground-based radar installations are driving next-generation analytics for large-scale projects in the fields of civil engineering, mining, transportation, and archaeology. Incredibly precise, 24-hour monitoring and observation of structures and landforms is possible using interferometric synthetic aperture radar (InSAR), or ground-penetrating radar (GPR).
Interferometric Synthetic Aperture Radar
InSAR is used for remote monitoring of slope movement and deformation in landslide areas or open-pit mines. This reduces risk to personnel, and can characterize a landslide's structure in a matter of days, instead of 6 months or more. In the case of mines, interferometry radar can continually monitor earth structure that is constantly being altered.
Ground-based radar can be deployed to conduct assays detecting damage and stress to infrastructure asset components such as concrete bridge decks, and roads.
In civil engineering applications, extremely minute tilting or subsidence can be detected by continuous monitoring of dams, bridges, and highway infrastructure such as overpasses and causeways.
In these environments, movement can be detected in increments as small as 1/10 mm (1/250 inch).
Ground-penetrating radar can be deployed to conduct assays detecting damage and stress to infrastructure assets. This technology can also image and create 3D maps of underground utilities.GPR can assess the structural integrity of concrete bridge decks and roadbeds, allowing engineers to rapidly determine any corrective action, and reducing the need for lengthy, disruptive, and expensive traditional methods.
Precise underground mapping of utilities in real-time 3D offers a game-changing alternative. The condition of infrastructure such as electrical and water networks can be rapidly and accurately assessed, allowing selective interventions for repair and retrofit. With public utilities budgets stretched across North America, this type of solution can save significant amounts of time and money while executing upkeep and replacement operations.
