| 摘要: |
| 基于建立的双层背腔微带天线共形阵模型，提出了一种改进的互耦修正投影法，并成功用于该类共形阵列的方向图综合。通过引入包含空间位置信息的广义阵元方向图概念，完成了对阵元激励幅相的同步求解；将阵元有源方向图思想与最小二乘法结合，简化了互耦系数矩阵的提取；综合过程计入了阵元相位方向图的贡献，使该方法的可靠性显著提高，阵列综合结果与全波分析结果的完全吻合，验证了该方法的正确性。 |

| Abstract: |
| An improved mutual coupling modified projection method was proposed, based on the two stacked patches back cavity microstrip conformal array model. The method was applied for synthesizing the patterns of this kind of conformal array successfully. The amplitude and phase of the element exciting can be solved at one time, by means of introducing the generalized element pattern including the location information. Meanwhile, the concept of the element active pattern was combined with the least square method to simplify the solved process for mutual coupling matrix. Moreover, the phase pattern was also considered, which improved the reliability of the synthesis method. Besides, the perfect agreement between the synthesized results and full-wave method confirms the validity of the proposed method. |
