Microwave Interferometric System for GPR Positioning

Ground penetrating radar (GPR) systems are sensors that able to acquire underground images by scanning the surface of soil/pavement under investigation. Usually, a GPR system records its own position along scan line, using mechanical odometer, i.e., rolling wheel in contact with ground. This simple and cheap solution can be ineffective on uneven terrains. In this paper, positioning based an interferometric is presented. kind detect small displacements targets field view. Such capability was used track line. The validated simulations tested realistic experimental scenario.
