Many works have been developed to compute RCS from this surface. The Classical Moment Method became an effective tool since it works for a very large class of surface shapes and scattering mechanisms. However, it requires a small mesh step ( =10) which produces a high number of unknowns. Besides, for a highly curved surface like the sea, we need a much smaller mesh step to avoid the factitious geometric discontinuities between the patches. In this work, we propose to use the Higher-Order Moment Method (HO-MoM) with NURBS patch to increase the mesh step into . We show that this method can solves the scattering problem with fewer number of unknowns. %G English %2 https://ensta-bretagne.hal.science/hal-00636394/document %2 https://ensta-bretagne.hal.science/hal-00636394/file/RefzulKhairi.pdf %L hal-00636394 %U https://ensta-bretagne.hal.science/hal-00636394 %~ ENSTA-BRETAGNE %~ ENSTA-BRETAGNE-STIC %~ ENSIETA-E3I2
