摘　　要：给出直线阵列天线的辐射散射特性阵元间距折中设计方法。运用该方法对8单元贴片阵列进行仿真验证,结果表明设计的贴片阵列可以在满足辐射性能的基础上,带内和带外单站RCS的强散射点得到了有效抑制,使其在绝大多数入射角处于低散射状态,从而证明了该方法可以快速、有效地指导兼顾辐射性能的低散射阵列设计。The radiation performance and low scattering property of a linear array are designed by adjusting the element spacing of a uniform array in this paper. An 1 -8 patch array antenna is designed using both this novel technology and the conventional one. Compared with traditional array design, the inband and outband RCS spots of strong scattering are considerably reduced, and the proposed method makes be at the status that it scatters with low level for most incident angles. The results show that the proposed method is feasible and effective for designing the antenna array.
