Quantification of Noise Sources in EMI Surveys Technology Demonstration Report Army Research Laboratory Blossom Point Facility, Maryland July - September, 2006
Abstract
This demonstration was conducted at the Army Research Laboratory Blossom Point Facility between July and September 2006. The magnitudes and effects of several types of background and/or noise sources on the data collected with several commonly used EMI sensors were measured. These noise sources included ground response/geology, inherent sensor noise, external noise sources, motion-induced noise, and position uncertainty. Using Monte Carlo simulations, the impact of each noise source on the final fitted parameters result was determined. Additional measurements were conducted at Blossom Point and other nearby locations to help separate the individual contributions of the convolved sources. The Blossom Point site was found to provide a good benchmark for a site where it should be feasible to conduct a survey-mode EMI survey. Two recommendations are provided as to a set of EMI sensors and a demonstration protocol to be used for future demonstrations. From these results, we can begin to understand real world EMI survey noise sources, and quantify these effects in terms of meaningful survey configuration parameters, such as lane spacing.
