Forward-Looking Ground-Penetrating Radar: Subsurface target imaging and detection: A review

Detection of shallow-buried, in-road threats using a forward-looking (FL) ground-penetrating radar (GPR) system has attracted significant research interest in the last decade. An FL-GPR mounted on a moving platform can provide standoff target detection and imaging. This enables real-time sensing and situation awareness over large ground areas. The main challenge facing this sensing technology is high false-alarm rates due to scattering arising from air–ground interface roughness and subsurface clutter.
