Traffic-speed surface & subsurface measurement platform

Overview:

Kerberos™ is a fully-featured sensor platform designed to investigate current conditions and determine “as-constructed” details of roads, airport pavements, bridges and other types of paved civil infrastructure at traffic-speeds. The modular & scalable design allows it to be installed on collection vehicles of different shapes and sizes or on a dedicated collection trailer.

Customers often seek out Kerberos™ because of its advanced 3D Noise-Modulated Ground Penetrating Radar (NM-GPR) subsurface imaging capabilities. While this is a key feature, it is only part of the platform’s investigative and measurement capabilities.

Platform features & capabilities:

• Continuously image and measure features above and below ground within normal traffic flows at up to 100km/hr [60MPH], avoiding the need for traffic control
• Uses 3D NM-GPR, the world’s fastest and most detailed traffic-speed ground penetrating radar (GPR) subsurface imaging technology
• Compliant & authorized to US & Canadian GPR UWB requirements [US FCC ID: 2BKW7-KerberosV21S; Canadian REL: 33089-KERBV21S]
• Uses a rugged, ground-coupled array that flexes with surface undulations for superior data quality, consistent coupling and protection from external interference
• Remote antenna array deployment/stowage without leaving the vehicle, for maximum operator safety
• Unrivalled data collection capacity & performance:
  • 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]
• Modular & scalable hardware that can be installed on various types of collection vehicle or on a dedicated trailer
• Ability to gather multi-offset GPR measurements alongside regular 3D GPR data, to enable advanced pavement permittivity analysis
• RTK-GNSS, IMU and a wheel encoder for accurate data positioning
• Optional synchronised 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
