Analysis and Validation of a Hybrid Forward-Looking Down-Looking Ground Penetrating Radar Architecture

Ground Penetrating Radar (GPR) has proved to be a successful technique for the detection of landmines and Improvised Explosive Devices (IEDs) buried in ground. In last years, novel architectures safe fast detection, such as those based on GPR systems onboard Unmanned Aerial Vehicles (UAVs), have been proposed. Furthermore, improvements hardware signal processing techniques resulted more efficient detection. This contribution presents an experimental validation hybrid Forward-Looking–Down-Looking architecture. The main goal this architecture is combine advantages both architectures: reduction clutter coming from ground surface case Forward-Looking (FLGPR), greater dynamic range Down-Looking (DLGPR). Compact radar modules working lower SHF frequency band used architecture, which involved realistic targets.
