High-Precision One-Dimensional Deformation Measurement Radar from China Suppliers and Factory for Bridge Monitoring
Product Introduction
One-dimensional deformation radar is a product based on high-resolution radar remote sensing imaging and phase interferometry measurement technology, using electromagnetic waves as the medium to conduct real-time, dynamic, and non-contact measurements of small deformation variables in targets such as bridges, high-rise buildings, towers, and tunnels.
The radar system consists of a deformation radar host, a display control terminal, a support component, and a power supply component. The display control terminal connects to the deformation radar host via a wireless network, and one display control terminal controls one deformation radar host to achieve one-dimensional deformation measurement of the target.

Frequently Asked Questions
QWhat is a one-dimensional deformation radar and how does it work?
A one-dimensional deformation radar uses high-resolution radar remote sensing imaging combined with phase interferometry measurement technology. It emits electromagnetic waves toward a target structure and analyzes the returned signals to measure tiny deformations in real time — without any physical contact with the structure.
QWhat types of structures can this radar monitor?
The radar is suitable for a wide range of civil and structural engineering targets, including bridges, high-rise buildings, towers, and tunnels. It has already been successfully deployed in more than 150 bridge projects for long-term structural health monitoring.
QWhat is the measurement accuracy of the deformation radar?
The deformation measurement accuracy is ≤0.1mm and the fundamental frequency measurement accuracy is ≤0.01Hz. The data update rate reaches ≥200Hz, enabling high-frequency, millisecond-level dynamic monitoring for precise structural analysis.
QDoes installation require attaching sensors directly to the monitored structure?
In most cases, no. The radar typically operates remotely at distances of up to ≥500m without requiring any targets or sensors to be physically installed on the measured structure. This significantly reduces installation time, deployment complexity, and overall project cost.
QCan the radar operate reliably in harsh outdoor environments?
Yes. The device features excellent environmental adaptability with an IP66 protection rating. It is unaffected by rain, snow, fog, or day/night lighting changes, and can operate continuously 24 hours a day, 7 days a week — making it ideal for unattended, long-term field monitoring.
QHow is measurement data processed and transmitted?
The system uses an edge computing architecture, meaning all signal processing and calculations are completed within the device itself. Measurement data is automatically saved to files for subsequent analysis and can be transmitted remotely. The display control terminal connects to the radar host wirelessly, providing real-time visualization and control.
