China Suppliers Factory: Advanced One-Dimensional Deformation Measurement Radar for Real-Time 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.
