Synthesis of unequally spaced arrays with uniform excitation is considered in this article. An iterative method based on second-order cone programming is developed to search the geometry with local optimum peak sidelobe level (PSLL), which is valid for arrays of different scale regardless of geometry constraints like centrosymmetry and minimum separation. By statistical analysis and comparison with other methods, it is verified that the computational complexity of the proposed method is only related to the dimension of optimization variables, and it can further exploit the potential of unequally spaced arrays with uniform excitation under acceptable complexity.

通过迭代二阶锥规划合成具有均匀激励的不等距阵列

本文考虑了具有均匀激励的不等距阵列的合成。开发了一种基于二阶锥规划的迭代方法来搜索具有局部最优峰值旁瓣电平 (PSLL) 的几何结构，该方法适用于不同尺度的阵列，而不受几何约束（如中心对称性和最小间距）的影响。通过统计分析和与其他方法的比较，验证了所提方法的计算复杂度仅与优化变量的维数有关，在可接受的复杂度下，可以进一步挖掘均匀激励不等距阵列的潜力。
