| 摘 要： | 1 Introduction Radar cross section(RCS)is one of the main parameters that estimate the stealth performance of aircraft. The theory of RCS is based on the scattered field created by the model subject to electromagnetic scattering, and the estimation is made through applying various kinds of computing method and technology to compute the RCS of the model under the circumstances 1]. There are two approaches to analyze RCS at present, one is testing the real model; the other is computing wit…

| Abstract: | An algorithm of trimmed surface triangulation is put forward by using the isoparametric curves of aircraft surfaces to evenly allocate the mesh nodes. Further refinements are made to deal with the trimming loops and ensure the mesh consistency. |
