A Ground Penetrating Radar Demonstrator for Fundamental Studies and Educational Purpose

In this contribution a ground penetrating radar demonstrator setup is discussed with a multi-bistatic antenna configuration for fundamental studies on object detection and localization. Broadband measurements from 100 MHz to 10 GHz with a network analyzer are conducted and analyzed both in the frequency and time domain. Measurement results are discussed with respects to several fundamental issues regarding object detection and identification, such as spatial and amplitude resolution, dynamic range and measurement time. In particular, the effect of antenna coupling and its effect on the measurement results are investigated. Finally, educational aspects in high frequency engineering are discussed considering the measurement setup itself as a complex system that requires expertise in a lot of other interdisciplinary fields, e. g. signal theory, filtering, and data analysis.
