The error cause analysis in EM simulation of ship

摘要

To ensure validity and applicability of computation results,the EM characteristic of a ship must have a full embodiment in the simulation.In this paper,concerning EM environment,configuration feature and RF function requirements of a ship,illustrates EM characteristic and error cause from two aspects,i.e.EM simulation model,computation and analysis method.Aiming at a typical example,analyzes the error in EMC simulation and RCS computation.It is proven that complex EM characteristics of a ship bring huge difficulty to accurate simulation,and the simulation modal and computation method are tightly connected to ensure the veracity of the simulation results.
