Abstract:

The objective of this project was to conduct a proof-of-principle demonstration that a single, fixed gradiometer or vector magnetometer could track an active EM sensor at sub-centimeter position and sub-degree accuracy over short baselines. We have shown that the concept of locating a UXO cart via the measurement of its transmitter signal is sound. Further work is warranted to develop a more precise system. Some of the areas that we recommend pursuing are Develop and trial a refined model of the transmitter source for inversion optimization investigate the potential of other sensors investigate the observed unexpected limitation in both the fluxgate and SQUID sensor systems signal to noise ratio determine the level of accuracy obtainable when the cart is in motion Develop and trial improved signal processing and inversion algorithms and investigate the feasibility of using the technique within the marine environment.
