摘要
在线性阵列天线方向图无约束Gram-Schmidt(G-S)正交化综合方法基础上加入零点导数约束条件实现宽零陷波束图综合。此方法保持了无约束正交化方法中因采用对阵列导向矢量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,此零点约束正交方法能很好实现在零阶、一阶和二阶导数约束条件下线性阵列波束图的综合。
Based on the Gram-Schmidt(G-S) orthogonal method for pattern synthesis of linear array without con- straints, null derivative constraints are proposed to implement pattem synthesis with broad nulls. The advantage of the simplified computation due to steering vector orthogonalization in unconstrained orthogonal approach is maintained, and the uniform or non-uniform linear army pattern synthesis can be realized by this method. The experimental results show that the null constrained orthogonal approach can fulfill linear array pattern synthesis with constrains such as null constrains, first-order and second-order derivative null constraints.
