— 本文提出了一种使用数字辅助米尔斯交叉阵列架构进行接收器引导天线细化的新方法。首先,我们推导出 M × N 单元的各向同性辐射器平面矩形阵列的功率模式。在下一步中,我们使用两种实现方法复制这些功率模式,从而形成数字辅助米尔斯交叉阵列。第一种方法使用乘法块,而第二种方法使用卷积块,两者都在数字域中。通过我们提出的技术,分别使用 41 和 21 个元件重新创建 121 个元件 30 dB Dolph-Chebyshev 均匀矩形阵列的功率模式。提出并讨论了验证理论结果的模拟结果。
— This paper presents a new approach for receiver steered antenna thinning using a digitally assisted Mills cross array architecture. First, we derive the power patterns of an M × N element planar rectangular array of isotropic radiators. In the next step, we replicate these power patterns using two implementation approaches which result in digitally assisted Mills cross arrays. The first approach used a multiplication block, while the second approach used a convolution block, both in the digital domain. The power patterns of a 121 element 30 dB Dolph-Chebyshev uniform rectangular array are recreated using 41 and 21 elements respectively by the techniques we propose. Simulated results, verifying the theoretical findings, are presented and discussed.
