System Main Features
Designed and operated in parallel, it is equivalent to four single-channel radars working simultaneously, significantly enhancing detection speed and inspection efficiency
The channels work independently, avoiding mutual interference and improving data acquisition quality
Strong flexibility and compatibility, allowing free selection of the number of channels and antenna frequencies based on needs
High-speed data acquisition, with a maximum of 512 scans per second per channel at 512 sampling points
Integrated design and abundant interfaces, superior protective performance, interfaces include serial port (RS232), RJ45, USB, and other expansions
The tow structure, similar to a trailer connection, ensures reliability and flexibility, allowing flexible forward, backward, and turning movements. The cart structure and radar can safely operate and detect at speeds around 70Km/h, providing high detection efficiency
Applications
Quality inspection of urban roads and airport pavements
Detection of voids and defects in urban roads
Pipeline detection
Tunnel and railway inspection
Asphalt layer, structural layer thickness, and defect detection during highway acceptance
Detection of structural layer and sub-grade defects in highways
