摘　　要：以SCTE可视化预估系统为基础,用高频近似法建立了考虑天线方向图时目标近场RCS理论模型.通过实例,计算了有无天线方向图影响下的近远场RCS曲线,分析了天线方向图对目标近场RCS特性的影响.结果表明,天线方向图对目标近场散射特性影响是不容忽视的.Based on SCTE（Scattering from Complex Target and Environment） visual prediction system,under the influence of antenna pattern,the theory model about targets near-field scattering is established with high frequency approximation method.Then the near-field and far-field RCS curves are presented combined with practical examples.The paper analyses targets near field scattering characteristics under the influence of antenna pattern.The research shows that antenna pattern can＇t be be ignored in near-field scattering.
