Impulse Radar Auto-Calibration


Impulse Radar Auto-calibration represents a new era in non-destructive pavement investigation. 

The system was developed by Impulse Geophysics for the purpose of high speed impulse radar road investigation to image the subsurface pavement structure to find the thickness, construction types and changes and anomalies, without disruption to traffic flow. Major advances in the technique were possible through innovative software which was developed 
in-house by Impulse Geophysics.

This allows impulse radar surveys to be carried out without the requirement of coring for calibration purposes. The Auto-calibration system continuously monitors the calibration velocity thereby negating the need for cores. Cores are only required for accurate identification of material types. The technique has been tried and tested by the UK Highways Agency.
