摘　　要：隐身飞机已逐步成为大国重器,并将持续发挥重要影响,隐身技术也已成为飞行器设计的关键技术。隐身飞机的雷达散射截面积(radar cross section,RCS)测量是设计、制造、维护隐身飞机的必要手段。从缩比模型的RCS测试、全尺寸飞机室外RCS测试、全尺寸飞机室内近场测试三个方面,回顾了隐身飞机RCS测量的基本流程,总结了隐身飞机RCS近场测量的理论基础,并着重对具有成像诊断功能的近场RCS测量技术进行了梳理与分析。对隐身飞机RCS测量的应用趋势和关键技术进行了总结与展望,有利于对隐身飞机RCS测量形成总体性了解,并把握RCS测量的发展方向。Stealth aircraft has gradually become a great power,and will continue to play an important role,making stealth technology become the key technology of aircraft design.RCS(radar cross section)measurement of stealth aircraft is a necessary step to design,manufacture and maintain stealth aircraft.The basic process of RCS measurement of stealth aircraft was reviewed from three aspects:RCS test of scaled model,outdoor RCS test of full-scale aircraft and indoor near-field test of full-scale aircraft,the theoretical basis of RCS near-field measurement of stealth aircraft was summarized,and the near-field RCS measurement technology with imaging diagnosis function was analyzed intensively.The development trend and key technologies of stealth aircraft RCS measurement were prospected,which is helpful to have a general understanding of RCS measurement of stealth aircraft and grasp the development direction of RCS measurement.
