| 摘 要： | 分析了任意结构基阵波束优化的稳健性。首先从理论上推导了阵列误差、权向量误差和权向量范数等因素与波束旁瓣畸变之间的关系,并利用优化波束的白噪声增益和权向量范数之间的关系,提出了任意结构基阵波束优化时权向量范数约束上限的选取方法。针对圆阵进行了大量的计算机仿真,分析了不同权向量范数约束条件下获得的优化波束的稳健性,证明了理论推导的正确性。

| Abstract: | The robustness of beampattern optimization for arbitrary geometry arrays is studied in this paper. Based on the sensitivity analysis of beampattern,the close form formula for sidelobe distortion of beampattern is deduced as a function of array perturbations and weighting vector norm. Using this sidelobe distortion formula,a criterion to select the upper limit of weighting vector norm with required robustness is proposed. The effectiveness of the proposed criterion and correctness of this analysis is verified by com-puter simulation. |
