【摘要】：在端射天线组阵中,由于天线单元间的复杂互耦,端射天线小间距组阵时副瓣电平抬高得不到预期增益的提高,通过拉大单元间距可以抑制互耦、获得高增益,但又导致出现栅瓣电平.基于此,提出一种基于平板端射天线内插虚拟阵元的新型组阵方法——数字虚拟端射组阵方法,并对侧向组阵时该方法的数字波束合成结果与实际端射天线阵的三维电磁仿真软件(CST)仿真结果进行对比分析,最后,通过实验测试验证了该方法对于抑制端射天线阵栅瓣的有效性.
[Abstract]:Because of the complex mutual coupling between antenna elements, the sidelobe level elevation can not be improved in the antenna array with small spacing, and the mutual coupling can be restrained by enlarging the cell spacing, and the high gain can be obtained. But it leads to the gate lobe level. Based on this, a new array method, digital virtual end-emitter array, is proposed, which is based on the interpolation of virtual array elements. The results of digital beam synthesis in the lateral array are compared with the results of the 3D electromagnetic simulation software (CST) of the actual end-launched antenna array. Finally, The experimental results show that the proposed method is effective for the suppression of terminal antenna array gate lobes.
