飞行器射频系统隐身表征与测试评估方法现状及发展

Review of Stealth Characterization and Measuring Evaluation Techniques of Aircraft RF Systems

射频隐身、雷达隐身是飞行器降低隐身威胁区域和敌方截获概率实现隐蔽突防作战的关键。如何有效并客观地评估飞行器射频系统的雷达隐身与射频隐身效能是否满足作战任务需求尤为重要。该文回顾了国内外雷达隐身和射频隐身的表征参量和测试评估方法,总结了关键技术特点及存在的不足,给出了射频系统隐身表征与测试评估建议,为检验实战环境下飞行器射频系统的隐身性能提供了参考。

Radio frequency(RF)stealth and radar stealth are two approaches to decrease threatened area and probability RF stealth and radar stealth are two approaches to decrease threatened area and probability of intercept,which are the key factors of stealthy penetration combat.It is essential to efficiently and objectively evaluate performances of the RF stealth and radar stealth efficiency of RF system of aircraft for special combat missions.In this article,the research progress of parameter characterization and evaluation methods for stealth capabilities are introduced and reviewed,and the technical features and drawbacks of these methods are also summarized.Several advices of stealth characterization for RF systems are proposed,which may be beneficial to evaluate stealthy performances of aircraft in actual combat environment.
