An advanced synthetic aperture radar (SAR)-based deformation monitoring system
The 4DSkin solution from Sixense is an advanced synthetic aperture radar (SAR)-based deformation monitoring system designed for non-contact measurement of large-scale ground and structural movement. Using radar interferometry, 4DSkin simultaneously measures the displacement of thousands of points over areas spanning several kilometres, providing high-precision deformation data without requiring physical access to the monitored zone. This makes it ideal for challenging environments where site access is limited, ensuring safety and efficiency in even the most demanding monitoring projects scenarios.
4DSkin operates by scanning the target area at regular intervals — typically every two minutes — to capture continuous surface movement data with sub-millimetric precision across the entire field of view. The radar system functions remotely and delivers high-frequency, real-time insight into deformation patterns regardless of weather conditions, and without the need for onsite intervention. The solution generates richly detailed displacement maps and time-series charts, empowering engineers and project teams to visualize evolving ground behaviour and identify potential risks proactively.
4DSkin is used on projects that require reliable, wide-area deformation monitoring — from landslide and rock instability surveillance, to open-pit mining operations, dam embankments and critical infrastructure monitoring over expansive zones. Its rapid deployment and remote capabilities help reduce installation time and logistical complexity while delivering actionable data that supports safety decision-making and risk mitigation. When integrated with Sixense’s data platforms, 4DSkin enhances situational awareness and enables stakeholders to respond quickly to evolving geotechnical conditions, making it a powerful tool for proactive management of geotechnical and structural risk.
