论文摘要
在本文中，通过采用术语的叠加，具有不等的系数，提出了一些有用的大平面阵列的有用的封闭式公式，以预测辐射梁的暂定性。尽管应用了简化的假设，但提供的公式可用于设计具有指定功率模式的大型多光束平面阵列。提供了几个说明性示例，这些示例在数值上通过MATLAB软件证明。所提出的合成方法的适用性通过模拟和理论预测之间的合成性验证。此外，研究了量化和阵列维度对控制功率性能的影响以及最大扫描角度的局限性。据信，所提出的直接方法的阵列合成方法为各种应用（例如多目标雷达系统和波束形成阵列天线）提供了新的机会。
In this paper, by adopting the superposition of terms with unequal coefficients, some useful closed-form formulas for the class of large planar arrays are presented for predicting the directivities of radiated beams. Despite the applied simplifying assumptions, the provided formulas may be used for designing a large multiple-beam planar array with a specified power pattern. Several illustrative examples are presented which are numerically demonstrate by the MATLAB software. The applicability of the proposed synthesis method verified by the achieved conformity between the simulations and theoretical predictions. Furthermore, the impact of quantization and array dimensions on the performance of power controlling as well as the limitations on the maximum scan angle are investigated. It is believed that the proposed straightforward approach for array synthesis provides a new opportunity for various applications such as multiple-target radar systems and beamforming array antenna.
