摘　　要：智能蒙皮天线能够将集成微带天线和传感元件嵌入到各类武器平台结构中,不仅具有电磁收发和力学承载性能,同时还具有服役状态感知与性能自适应功能。为了解决蒙皮天线因结构变形导致的电性能恶化问题,文中提出了一种嵌入光纤光栅的智能蒙皮天线结构,并利用模态分析和状态空间理论,从少量光纤光栅测量的应变实时重构天线结构的变形位移场。通过研制的智能蒙皮天线结构变形实验系统,验证了变形位移场重构方法的有效性。该位移场重构方法为智能蒙皮天线电补偿系统的研制奠定了基础。Smart skin antenna can embed integrated micro strip antenna and smart sensors into all kinds of weapons platform structures. Not only does it have the function of electromagnetic transceiver and the mechani- cal bearing performance, but also it has the function of working state perception and performance. In order to solve the deterioration problem of electrical performance resulted from the smart skin antenna structure deform- ation in the severe environment, this essay invents a new type of smart skin antenna into which the optical fiber is embedded , and reconstructs the antenna deformation displacement from the strain measured by the small amount of the optical fiber in real-time, based on the modal analysis and state space. With the experiment sys- tem of smart skin antenna structure deformation, the effectiveness of the deformation displacement reconstruc- tion method is testified. This deformation displacement reconstruction method makes a base for the research of smart skin antenna electrical compensation system.
