摘要
环境载荷严重影响共形阵列天线的电性能,对研究和发展高性能共形天线而言,环境载荷是一个不容忽视的问题。文中从变形面的拟合出发,提出了一种变形后天线电性能的计算方法,利用此方法计算随机振动下共形阵列天线的电性能,分析随机振动对共形阵列天线电性能的影响。文中所提方法与结论可为工程技术人员设计高性能共形天线提供参考。
Environmental loads have serious influence on the electromagnetic performance of conformal array antennas, so it can＇t be ignored for the research and development of high-performance conformal array anten- nas. Based on the fitting of the deformed surface, a calculation method for the electromagnetic performance of the deformed antenna is proposed. The electromagnetic performance of the eonformal array antenna under ran- dom vibration is calculated by this method, and the effects of the random vibration on the electromagnetic per- formance are analyzed. The method and the calculated results provide reference for engineers to design high- performance conformal array antenna.
