Rail Radar^® system provides fully integrated non-destructive track data collection and analysis capabilities:

• Ballast inventory and assessment using patented GPR post-processing and analysis.
• Tie and fastening systems inventory and assessment using digital image post-processing and analysis.
• Rail joints and OTM using digital image post-processing and analysis.
• Precise positional referencing using differential GPS, linear measurement and track landmark tie-in.

Objective and repeatable track assessments also make Rail Radar^® well suited for:

• Forensic track analysis
• Assist with due diligence and regulatory compliance evaluations
• Combine with a Track Information Management System or Track Network GIS for comprehensive life-cycle cost and track performance analyses.

Data Collection Parameters
Rail Radar^® data is acquired with a current maximum data collection speed of 40kph (25mph) and is post-processed to provide ballast and tie structural and material property parameter measurements at each radar data collection point. The Rail Radar^® antenna array has been optimized for rail applications and can be configured to conduct surveys between or outside of the rails as required.

• Ballast Assessment using Patented GPR System
• samples acquired at any programmed distance
• every 25-50mm (1-2 inches)
• layers resolved as thin as 40mm (1.5 inches) to a depth greater than 1.5m (5 feet) in normal railbed structures
• a layer thickness measurement accuracy of ±5%
• able to survey through wooden or reinforced concrete (PCC) ties
