Modeling water level´s heaving and low-frequency Electromagnetic response from the highly conductive object submering in water environment

In this paper we present simulation results, which illustrate how water level´s heaving, can influence on low-frequency magnetic response of the electrically highly-conducting object placed in water environment. The time domain problem is solved using interpolation of partial solutions obtained in the frequency domain. In the frequency domain Electromagnetic problems are solved using the method of auxiliary sources. GEM sensor is modeled as excitant in the electromagnetic problem. Presented results estimate capabilities of the low frequency EMI in the detection and the discrimination of an unexploded ordinance (UXO) in water environment.
