Traffic-speed surface & subsurface measurement platform

Features:

• Uses 3D NM-GPR, the world’s fastest ground penetrating radar (GPR) technology, for rapid subsurface assessment of large & complex sites
• Scan roads within the normal traffic flow, avoiding need for traffic control
• Deploy the array and scan without leaving the vehicle, for maximum operator safety
• Unrivalled data collection performance, without compromise:
  • Densely spaced, high-resolution data with superior penetration at traffic speeds
  • Typical configuration: Measuring on 30 GPR channels (4 pods) at 25mm intervals in the direction of travel, penetrating to ~3.0m max. depth (assuming favourable site materials) with ~1.2 GHz centre frequency resolution at 100 km/hr [62 MPH]
• Rugged, modular array that flexes with surface undulations for superior ground-coupled data quality, consistent coupling and protection from unwanted aboveground feature reflections and external interference
• Modular & scalable hardware that can be used on a collection trailer or vehicle
• Ability to gather 3D subsurface imagery and multi-offset GPR data in the same pass, for advanced analysis
• RTK-GNSS, IMU and a wheel encoder for accurate data positioning
• Optional sensors & enhancements:
  • Continuous road surface imaging camera
  • Visible light or IR surface lighting arrays
  • Environmental / ROW cameras
  • Transverse laser profiling (for rutting measurements)
  • Wheel-path laser measurement of longitudinal roughness, texture
  • LiDAR
