Evaluating RCS of 3D Objects Using FV-FD Hybrid Algorithm and the Parallel Implementation

摘要：

A FV-FD hybrid algorithm is proposed by presentinga novel connecting condition between the two algorithmswhich march in time in different schemes.The reflection errorinduced by the connecting boundary is analyzed.The RCS of a3D PEC sphere is calculated as a numerical example,whichshows that the hybrid algorithm has the advantages of higheraccurate,reducing running time and saving computationalmemory.Then the Shared-memory parallel programming isapplied to the hybrid algorithm and a high parallel efficiency isachieved.
