The Different Types of Radars in Mining & Engineering
Slope Stability Radar (SSR) technology plays a vital role in mining and engineering, offering advanced solutions for monitoring slopes, detecting movement, and ensuring safety. With various radar types available, selecting the right one for a specific application is crucial.
Every mine site has unique challenges and requirements. GroundProbe has developed the industry’s broadest range of radar technologies and services to help predict and respond to even the most complex geotechnical conditions.
Below is an overview of the different types of radars used in mining and engineering, along with their key functionalities.
Ground-Based Radars
Ground-based radar sensors are extensively used in mining and geotechnical applications to monitor slope stability and detect movement. These radars use high-frequency radio waves to scan the terrain, providing real-time data on potential instabilities.
- Designed to detect early stages of deformation or ground movement, allowing geotechnical engineers to make confident, data-driven decisions.
- GroundProbe’s SSR-XT, SSR-Omni, and SSR-FX are industry-leading Real Aperture Radars (RAR), offering high precision and reliability.
- The SSR-SARx is a Synthetic Aperture Radar (SAR) designed for long-range monitoring, identifying risks and hazards over extended periods.
Satellite-Based Radars
Interferometric Synthetic Aperture Radar (InSAR):
- Used for large-scale surface movement detection, making it ideal for long-term monitoring of tailings dams and extensive mining sites.
Doppler Radars
Doppler radars are essential for rockfall detection and safety monitoring. These radars measure the velocity of moving objects, making them ideal for tracking falling rocks and ensuring rapid response times.
- GroundProbe’s RGR-Velox is a high-precision Doppler radar that delivers instantaneous alerts in the event of rockfall hazards, improving operational safety.
Real Aperture Radars (RAR) and Synthetic Aperture Radars (SAR)
The mining industry primarily uses two types of radars for geohazard prevention—Real Aperture Radar (RAR) and Synthetic Aperture Radar (SAR). GroundProbe is the only provider offering 3D RAR, 2D RAR, and 2D SAR across a fleet of five slope stability radars.
RAR and SAR technologies
- RAR and SAR are extensively used for surface deformation monitoring. These radars provide high-resolution imaging and can penetrate environmental obstacles such as fog and dust, making them highly reliable for continuous monitoring.

LiDAR and Radar Integration
While LiDAR and radar are distinct technologies, integrating them together into a monitoring strategy enhances precision in engineering applications. LiDAR is highly effective for mapping and topographical assessments, while radar sensors provide detailed movement analysis, ensuring a comprehensive understanding of site conditions.
