摘要: 文中在线性阵列天线方向图正交综合法基础上引入约束条件,实现阵列方向图的约束正交综合.此方法保持了非约束正交化方法中因采用了正交化处理而使得计算简便的优点.适合均匀或非均匀直线阵的综合.实验结果表明:约束正交综合法能很好地实现在主波束导向约束、零点约束、旁瓣电平约束等约束条件下的线性阵列方向图的综合;并且该方法只通过解析计算就能实现与需经多次迭代计算的自适应综合法相当的性能,计算量更小.

Abstract:

Based on the orthogonal method for the antenna pattern synthesis of linear arrays, some constraint conditions are proposed to implement a constrained orthogonal synthesis. The proposed method simplifies the calculation due to the orthogonalization in unconstrained orthogonal approach, and it helps to realize the pattern synthesis of uniform or nonuniform linear arrays. Experimental results show that the proposed constrained orthogonal approach can fulfill the pattern synthesis of linear arrays with such constrains as beam steering in a given direction, null steering and sidelobe level suppression, and that it is of similar performance to that of the iterative computationbased adaptive synthesis method but with simple analytical calculation.
