摘　　要：大口径高性能天线的电性能对外界复杂服役环境的干扰更加敏感,除了要保障机、电、热各学科本身的设计与制造水平之外,实现各学科的交叉融合下的服役性能调控也尤为重要。为解决大口径天线服役性能在工程实际中难以保障的难题,分别从大口径天线复杂服役环境下机电热耦合建模、服役环境状态信息传感布局与实时重构、基于多系统协同调控的机械/幅相综合性能补偿方法三个方面入手,综合调控大口径天线服役性能。在研究上述关键技术的基础上,结合工程应用需求,研发了大口径高性能天线状态监测与性能综合调控系统,在反射面天线、相控阵天线等典型工程对象中得到成功应用。工程应用结果表明,所提出的高频段大口径天线服役性能调控技术能够有效提升复杂环境下大口径高性能天线服役性能与可靠性,保障了大口径天线“看得更远、看得更清、看得更准、看得更稳”。With the aperture becomes larger and the working frequency becomes higher, the large antenna turns to be more sensitive to the structural deformation induced by the complex environmental loading. The unclear coupling relationship and mechanism among the electromagnetic field, the structural field and temperature distribution has significantly restricted the development of the high-performance large antenna. Apart from enhancing the design and manufacturing level, it is also important to regulate the antenna performance from the view of electro-mechanical coupling. Therefore, a performance regulation method based on the analysis of the large antenna electro-mechanical coupling, antenna structural sensing and reconstruction, and multi-system compensation method has been proposed to solve the current issue. A large antenna condition monitoring and regulation system has also been developed and applied in reflector antenna and phased array antenna to guarantee its performance. From the engineering application point of view, it is suggested the proposed method can successfully guarantee the detection performance and reliability of the large aperture antenna working in the complex environment.
