The importance of the non-acoustic signatures is increasing with improvements in detection technology and changing operational requirements which require an increasing number of operations in littoral waters. The electromagnetic signatures are a significant sub-set of the underwater non-acoustic signatures. It is known that the magnetic and Static Electric signatures present a mine threat. Degaussing is routinely used to reduce the ferromagnetic signature. The magnetic signature comprises another component, called the Corrosion Related Magnetic signature, which cannot be countered by using degaussing. As a result of the emergence of stealthier submarines, use of a-magnetic materials and improved degaussing equipment there is a shift in emphasis towards new signatures such as the Corrosion Related Magnetic signature. This paper examines the composite magnetic signature and explores the balance of importance between the ferromagnetic and Corrosion Related Magnetic signatures in the light of improving magnetic sensor performance. The investigation is illustrated using examples of ferromagnetic and Corrosion Related Magnetic signatures derived from simple models.
