GPR emissions and regulatory limits

Abstract

Regulatory emission limits now exist for Ultra Wideband (UWB) ground penetrating radar (GPR) in a number of jurisdictions. The regulations are defined using the concepts and terminology more suited to traditional narrow band radio transmitters. Limited theoretical and experimental information on the emissions from GPR devices have made arguing a compelling case for less stringent emissions levels extremely difficult. Further, the current regulations have the potential to trigger a review on current emission limits in the future. In this paper, we focus on the basic steps needed to translate GPR results into 'regulatory' parameters. We anticipate this will take several years. The ultimate goal is to provide the basis for more sensible rule making, if and when, the regulatory standards come under scrutiny for revision.
