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 compromise design method of radiation scattering characteristic array element spacing of linear array antenna is given. The simulation results of the 8-cell patch array show that the designed patch array can effectively suppress the strong scattering points of the single-station RCS in-band and out-of-band based on the radiation performance, Most of the incident angles are in a low-scattering state, which proves that this method can guide the design of low-scattering array with both radiation performance quickly and effectively.
