Abstract:
In order to analyze the scattering problem of electrically large bodies of revolution more efficiently,an acceleration method for the method of moments for bodies of revolution(B
OR-M
OM)using multi-level adaptive cross approximation(MLACA)is present in this paper and applied on the B
OR-M
OM based on the triangle and 3-order Hermits basis functions respectively. The MLACA is used to accelerate the filling process of the mono- and multi-mode impendence matrices of the B
OR-M
OM of combined field integral equation. The computed far-field RCS matches the numerical result of the traditional B
OR-M
OM well and the computing efficiency is improved considerably.
