摘　　要：利用复射线近轴近似法分析二维圆柱形磁性天线罩的电磁传输特性。分析了天线罩对罩内的雷达天线性能的影响。讨论了天线罩引起的传输系数和角跟踪性能的变化。数值结果表明,相对介电常数和相对磁导率相等的磁性天线罩具有最佳的电磁传输特性。The electromagnetic transmission performance of a 2-D cylindrical magnetic radome is analyzed by complex ray paraxial approximation method in this paper. The effect of radome on performance of radar antenna, radome transmission coefficient and radar angular track property are simulated. It is shown that radomes have the most optimized transmission performances if the relative permittivity of organic magnetic material equals to the relative permeability.
