Presentation by Isaak Tsalicoglou, Head of Product Management of Proceq, at the UK Concrete Show 2018 in Birmingham.
1) Overview of traditional ground-penetrating radar (GPR) and the key trade-off between penetration depth and target resolution.
2) Stepped-frequency continuous-wave (SFCW) GPR and its first-ever implementation in a handheld structural-concrete scanning device, Proceq GPR Live.
3) Experimental setup of comparison between Proceq GPR Live and two conventional pulsed GPRs; validation of superior performance of SFCW in terms of data quality, penetration depth, target resolution.
4) Real-world examples of looking into concrete: various data processing views of concrete slab data for rebar location, transition between asphalt and concrete road sections, reinforced pillar with and without steel-reinforced concrete (SFRC), scan of long floor with grade, scan of thin concrete slab with two aligned layers of thin rebar, slanted concrete block with various metallic and non-metallic targets (rebars, ducts), 50%-downscaled neigboring reinforced walls and SFCW GPR jumping the air gap between them.
5) Observation and conclusions.
