AB  - Calibration of ground penetrating radar (GPR) measurement systems isindispensable to enable quantitative and high resolution data analysisespecially for high resolution soil research as well as inversion approachesfor a wide range of applications. This work presents a concept for an in situcalibration of GPR monitoring systems which enables to perform acalibration that is not solely based on signals traveling in air. A classicalcalibration via signals traveling in air is not feasible in our setup, since thesystem is permanently positioned around a test specimen, e.g. a soil column.The calibration concept is based on the ability to use each antenna as bothtransmitter or receiver and, thereby, perform reciprocal measurements.Initial test measurements indicate the reliability of reciprocal measurementsfor an in situ calibration of our monitoring system with relative accuracies ofdown to 2 ps.
