Industrial societies are dependent on services delivered by infrastructure buried underground, principally in roadways and at intersections. Knowledge of sub grade and soil conditions, and locating and 3D mapping of underground features and infrastructure is essential when new infrastructure is added or roadways constructed. Ground Penetrating Radar (GPR) can accurately locate both metallic and non-metallic buried objects without prior knowledge of their position. Current GPR systems are limited in range and resolution and by human data interpretation. To address these challenges, IAI and its collaborator, IDS North America, have been awarded a contract entitled “GeoRad - Next Generation High Resolution, Long Range, Flexible and Modular Ground Penetrating Radar.” IDS’s existing state-of-the-art dual-frequency dual-polarized massive array GPR, called Subsurface Tomographic Radar Equipment for Assets Mapping (STREAM), will be leveraged. STREAM’s large array allows for rapid scanning of an entire intersection and its accuracy will be improved to map wires and pipes. This will be combined with IAI’s high-accuracy RF positioning, high-resolution Synthetic Aperture Radar (SAR) imaging, and innovative model-based inverse scattering target recognition technologies to achieve sub-foot accuracy and improve image quality. Use of low cost/high resolution point-to-point ranging capability of Ultra-wideband (UWB) radio will improve GPR’s positioning. With accurate positioning, the SAR imaging algorithm will coherently process over a large travel distance. The large aperture will provide high-resolution SAR images even for low-frequency signals, which can penetrate deeper into the soil. GeoRad is independent, highly reconfigurable and transportable and has high acquisition speed, accuracy, modular design, long range, high resolution, high feasibility and low technical risk. It can also be extended to other areas like mine detection, Improvised Explosive Device (IED) detection, archaeology and environmental studies.
