摘要
介绍了对星载成形反射面天线全域基设计法的研究。采用单馈源单反射面天线,通过优化反射面得到赋形波束。文章研究的全域基设计法运用物理光学法,将反射面用Jacobi-Fourier表达式展开,展开式各项的系数作为优化对象,代入反射面天线远场辐射积分的计算,在优化远场辐射特性的同时确定了反射面展开式各项的系数,也即确定了反射面。
This paper introduces the study of global design of the onboard shaped reflector antennas. Single feed and single reflector are used. The reflector is optimized to produce contoured beam. The global designs in this paper used PO method, deploying the reflector by Jacobi-Fourier expansion and calculate the far field characteristics with this expansion. The coefficients became the optimization objects. When the far field characteristics are optimized, the coefficients are gotten and the reflector is confirmed.
