| Abstract: | 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. |
