In this contribution, a novel Ground Penetrating Radar (GPR) configuration to detect low-contrast buried targets is presented. It is based on combining the advantages of Forward-Looking GPR (FLGPR) and Down-Looking GPR (DLGPR) using a distributed GPR system, with a vehicle-mounted transmitter looking ahead and a drone-mounted receiver looking downwards. This configuration provides good penetration and high resolution, reducing the clutter compared to DLGPR. Several simulations have been performed and the resulting Synthetic Aperture Radar (SAR) images have been compared.
