摘　　要：为实现天线雷达散射面缩减的目的,研究了隐身天线罩在吸收频带范围内斜入射时的双站雷达散射截面特性。仿真计算了6GHz、10GHz频率在垂直入射、20°斜入射与40°斜入射时的双站散射特性,并与金属结构的天线罩进行了对比分析。仿真结果表明:该型隐身天线罩的隐身效果良好。The antenna is a kind of strong radiative resource due to its characteristics of radiation. Therefore, the reduction of the radar cross section of the antenna is a challenge. The design of a ra- dome can greatly reduce the radar cross section. The research on the bi-RCS of the invisible radome, which is a novel and stealthy device, is rarely reported. This paper analyzes the characteristics of the bi-RCS for the radome rather than the structure, focusing on the characteristics of the bi-RCS with different frequencies such as 6 GHz and 10 GHz at the different incident angles like normal incidence, 20° and 40°. The comparative results show that the novel structures for stealth are better in performance.
