Quantification of Noise Sources in EMI Surveys
Abstract
A series of field measurements were made under carefully controlled conditions at our home facility at the Army Research Laboratory Blossom Point Facility between July and September 2006. The magnitudes and effects of several types of background and 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. By use of Monte Carlo simulations of the fitting process for a canonical object using the collected data, the impact of each noise source on the final fitted parameters result was determined and compared to a similar analysis done for the 4.2-in. mortar. Two recommendations are provided as to a set of EMI sensors and a demonstration protocol to be used for future demonstrations. We have attempted to quantify these effects in terms of survey configuration parameters that are under site manager and data collection operator control, such as lane spacing and survey mode.
