Effects of Target Corrosion on Advanced EMI Signatures in Underwater Environments (non-Acoustic)

Abstract

Munitions submerged in sea or fresh water for any length of time may become heavily rusted or encrusted with sea growth. At present there is very little hard empirical data on the effects of corrosion and biofouling in marine environments on the electromagnetic induction (EMI) and physical acoustic response signatures of military munitions. This research systematically examined the effects of two primary types of corrosion and biofouling that are commonly found in the underwater environment. A combination of laboratory tank tests and controlled exposure in real-world underwater environments were used. No measurable difference was seen between the EMI response of bare surrogates and those with the corrosion layers applied. We conclude without specifically demonstrating it that there would be little impact on acoustic detection ranges, classification performance, or maximum burial depth caused by a thin corrosion layer.
