Application of Differential Recursion Method in Depth Conversion of Ship Static Electric Field

doi:10.3969/j.issn.1000-1093.2018.02.018

Abstract

Abstract: For the divergence and curl of electric field generated by the ship, which are zero in the converted area, the first-order vertical partial derivative of node on the measuring plane can be calculated by using the horizontal partial derivative, and the recursion relation can be formed based on the Newton-Leibniz formula. A differential conversion method is given to convert the electric field distribution on the measuring plane to that on the target plane. The feasibility of the method is proved by using the horizontal electric dipole (HED) as the basic simulating unit of ship static electric field through simulation and experiment. Further analysis shows that the converting precision and efficiency of the method can be improved by changing recursive step, node interval and the distance between the sensors and the sea bed. Key
