This source provides a comprehensive technical guide for constructing a do-it-yourself (DIY) Ground-Penetrating Radar (GPR) system, detailing the fundamental physics of GPR operation, including how electromagnetic waves interact with subsurface materials to map hidden features. It surveys various documented DIY GPR projects, from simple microcontroller-based systems to advanced academic prototypes, highlighting different design philosophies. The text then focuses on the critical hardware components, such as ultra-wideband (UWB) transmitters and sensitive receivers, explaining their design and construction. It also addresses the software toolchain for data acquisition and processing, emphasizing open-source solutions for interpreting raw signals into subsurface imagery. Finally, the source evaluates the practical realities of DIY GPR, including cost, performance limitations compared to professional systems, the significant challenge of data interpretation, and the complex legal and regulatory hurdles associated with operating UWB radio emitters, while also suggesting alternative geophysical techniques for subsurface exploration.
