This paper aims to demonstrate, through practical examples and numerical modelling, the trade-off between range and resolution in ground penetrating radar (GPR) prospecting. GPR surveys can easily fail when the target and host rock properties and geometry are not well understood, resulting in an inappropriate choice of operating frequency. The authors include selected results from a 2D study aimed at investigating GPR performance across the frequency band 100-1000 MHz and also include selected case study results.
