The boundary element method (BEM) is introduced to analyze the boundary of the target by use of a matrix equation.

Active Electro-Location of Objects in the Underwater Environment Based on the Mixed Polarization Multiple Signal Classification Algorithm.This article proposes a novel active localization method based on the mixed polarization multiple signal classification (MP-MUSIC) algorithm for positioning a metal target or an insulator target in the underwater environment by using a uniform circular antenna (UCA).  In this method, an electric dipole source as a part of the locating system is set perpendicularly to the plane of the UCA.  As a result, the UCA can only receive the induction field of the target.  The potential of each electrode of the UCA is used as spatial-temporal localization data, and it does not need to obtain the field component in each direction compared with the conventional fields-based localization method, which can be easily implemented in practical engineering applications.
