Paper Abstract

The generation and recording of electromagnetic waves by typical ground-penetrating radar (GPR) sounding systems is complex and the effects of the antennas on the recorded data are not well understood. To address this problem, we present a versatile and efficient GPR system simulation tool. This algorithm is based on a finite-difference time-domain (FDTD) approximation of Maxwell's equations and allows us to model realistically the radiation characteristics of a wide variety of typical surface GPR antenna systems. The accuracy of the algorithm is benchmarked and validated with respect to extensive laboratory measurements for comparable antenna systems. Given the flexibility of this GPR modeling software, we anticipate that it will be useful not only for the design and interpretation of GPR surveys, but also for the design of novel GPR sounding systems.
