Paper Abstract

This work describes a target location estimation procedure for single channel 2-D electromagnetic induction (EMI) scan data for both a rotating and non-rotating sensor head. The location estimation technique is based on a new low-rank model for electromagnetic induction data and and addresses difficulties in how to efficiently construct the dictionary for inverting the single channel EMI data. The location estimation technique is tested on simulated data for a single z-directed wire loop for both a rotating and non-rotating sensor head, and on non-rotating sensor head laboratory measurements for four different mine types. The technique is shown to accurately estimate the target location for simulated data and experimental data, and is able to estimate the location of strong mine targets at depths of 20 – 30 cm with ±2 cm error.
