摘　　要：随着舰船隐身技术逐步发展到指标分配阶段，桅杆作为全舰雷达散射截面的重要焦点已逐渐受到高度重视，研究人员已把桅杆作为独立部件进行研究。通过应用RCS分析软件，全面分析了隐身桅杆RCS测量过程中角度、频率的影响，通过理论分析，推导出了隐身桅杆角度间隔、目标电尺寸和RCS平均值相对误差三者间的关系。在理论分析与资料收集的基础上，给出了隐身桅杆RCS测量频率表。With the development of stealth technology applied in naval ship, the mast as one independent component that contributs much to the RCS （ Radar Cross Section） test of ship, have been received much attention by naval architects. Software for RCS analysis is applied to investigate the influence factors of angle and frequency on RCS test of mast. Through the analysis in theory, the relations among angular space, electricity dimensions of target and relative error of mean numerical value in theory are found out. Lists of the frequency range for RCS test on steahh mast are therefore provided based on theoretical analysis and data collection.
