摘　　要：阵列天线的散射场由结构项散射场和模式项散射场2部分组成,在低RCS阵面设计过程中,两者互为主导,相互制约,必须同时有效克服。文中给出了一些天线结构散射场和模式散射场的减缩方法,仿真结果表明它们能够有效降低天线阵面的雷达散射截面,达到天线隐身的目的,具有较好的工程实用性。Radar cross-section(RCS)of array antenna can be separated to two parts,one is the common structural scat- tering component,and another is the antenna-mode scattering component.In the low RCS design processes,both of them are im- portant and interact with each other and should be reduced efficiently.Some methods of minimizing both the mode-scattering com- ponent and structural scattering component are given.Simulation results show that these methods can reduce the RCS of arrays effi- ciently.They can make an...
