Penetradar Corporation specializes in the inspection of large and complex bridge decks with our patented ground penetrating radar (GPR) four antenna array which allows simultaneous collection of radar data across a twelve foot lane in one pass. Four channels of radar data are collected with the same distance referencing eliminating inconsistencies in distance correlation between radar passes which are a problem associated with single and dual channel systems that must make multiple passes to cover a lane. With our system, we can scan large and complex bridge decks efficiently and economically in just a short time with a single pass over each lane collecting data at highway speeds, thereby eliminating traffic congestion, road closures and safety concerns.
