Multipolar Harmonic Model applied to UEP Source Identification"

Résumé

Corrosion or adapted cathodic protection is responsible for UEP (underwater electric potential) generation that may cause ship detection. As a consequence, ship electric signatures are measured on dedicated ranges at given depth. Nevertheless, to assess the threat, the signature must be known at larger distances and for different parameters (conductivity, water depth, number of conductive layers) depending on ship operation zone. In previous work, a dipolar model has been proposed to represent the electric field sources and exhibited good agreement with experiment. It was based on ellipsoidal harmonic decomposition and the use of image methods. The present paper deals with the generalization of the model to its multipolar components. After presenting the model elaboration, the approach is tested on numerical cases computed by CorOnS software, developed by the G2Elab in cooperation with the DGA (Direction Générale de l’Armement).
