摘要
研究标准目标的电磁散射特性,为目标电磁散射特性的研究提供理论依据。围绕标准目标电磁散射特性理论研究方法和雷达散射截面(RCS)的概念,讨论了常用定标体金属导体球的雷达散射截面的理论计算方法,用有限元法(FEM)计算了导体球的NRCS值和相位。计算结果与已给出金属导体球的NRCS值和相位值比较吻合,验证了该方法的可行性。
Research on the standard target electromagnetic scattering characteristic provides a theoretical basis for the target electromagnetic scattering characteristict in theory.Based on this,the paper focuses on the research methods of the standard target electromagnetic scattering theory and the concept of radar cross section（RCS）,and discusses RCS theoretical calculation method of the metal conductor sphere that is used as the standard in RCS measure.NRCS value and phase are calculated by finite element method（FEM）.Calculation result is consistent with the metal conductor ball of NRCS value and phase value that have been given.The feasibility of this method is verified.
