LGPR 3D Three-dimensional Array Radar System

    In the maintenance and management of modern transportation infrastructure, defect detection on highways is always a critical step in ensuring driving safety and road lifespan. The 3D GPR array data acquisition system includes radar array antennas (integrated host), GPS precise positioning system, control unit, engineering vehicle, etc. It synchronously collects various data information such as 3D ground penetrating radar images, image coordinate positions, and markers, and integrates them into the same dataset. This system can conduct comprehensive and full-coverage survey and detection of urban roads. By adopting the 3D GPR system, geophysical exploration technicians can analyze and determine the location, morphology, and hazard level of each underground anomaly through radar image "slices" from different directions.
