STEP-FREQUENCY RADAR APPLIED ON THIN PAVEMENTS

The paper presents the principle of the step-frequency technique. An ultrawide band antenna has been developed for road applications; it was created using "stripline" technology and yields a bandwidth greater than one decade, over a several gigahertz range. Ground penetrating radar (GPR) dynamic measurements were obtained from selected road construction and maintenance test sites. Results have shown improved resolution in comparison with commercial impulse GPR system.
