GPR works in a similar way to acoustics and the analysis of sound waves, however, with the use of electromagnetic waves in place; the principles are the same. A radar antenna will emit an electromagnetic pulse as a waveform that will propagate through a sub-surface body creating reflections. The time it takes for a waveform to travel from a transmitter and reflect back to a receiver can be used to determine the location and depth of an object. The speed at which a waveform travels through a body varies in range depending on the composition and potential saturation of that material.
GPR SurveysÂ
Ground penetrating radar (GPR) is a non-intrusive geophysical method used to locate and map sub-surface features.
Common applications are in the identification of utilities, concrete thickness, rebar, concrete structural analysis, and void determination. Beyond this, due to the versatility of GPR there is a wealth of applications that GPR excels at offering information on, from shallow surface geology and archaeology to subsurface environmental investigations.
