Sumario:A numerical approach for the reduction of the CPU time associated with the solution of electromagnetic problems with multiple right-hand sides is presented. This technique is especially suited to analyze the monostatic radar cross section (RCS) of electrically large cases, based on a novel interpolation approach over several directions and/or frequencies, reducing the total simulation time significantly while maintaining a good degree of accuracy. The test cases show that the approach provides accurate results for complex bodies and a noticeable reduction in the CPU time of the simulations.
