Semi-intrusive determination of ground penetrating radar wave velocity

摘要

A review of established techniques used to determine radar wave velocities within different materials is presented. A new semi-intrusive method for determining the velocity of impulse radar energy through materials is proposed based on the refraction of electromagnetic waves as they transmit through layers of different materials. Inserting a metal bar into the material and traversing the surface of it enables the impulse radar velocities of the material under investigation to be readily interpreted from the radargram. This new method provides a quick, readily interpreted and practical tool for ground penetrating radar operators to use.
