Application of Non-stationary EIV Methods to Transient Electromagnetic Mineral Exploration

In this paper, we apply a non-stationary errors-in-variables model estimation technique to a problem arising in transient electromagnetic mineral exploration. The proposed technique is used to estimate a model which is deployed for noise cancellation. Alternative methods for noise cancellation in these systems rely on specific signal characteristics, and are thus not readily transferable to other applications. The proposed technique produces an estimated model that agrees well with those obtained using alternative methods, and achieves noise reduction levels similar to those achieved via the alternative methods. This is shown by performance comparisons on experimental data. An advantage of the proposed technique is that it is more readily transferable to other applications.
