约束条件下的线性阵列天线方向图正交综合法

在线性阵列天线方向图正交综合方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更为简便的优点，能实现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，并且此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。

Orthogonal Method for Pattern Synthesis of Linear Array with Constraints

Based on the orthogonal method utilized for pattern synthesis of linear array, some constraint conditions are added to implement constrained orthogonal synthesis. The advantage of simplified computation resulted from orthogonalization in unconstrained orthogonal approach is maintained in the proposed constrained orthogonal method, and the uniform or non-uniform linear array pattern synthesis can be realized by this method. The experimental results show that the constrained orthogonal approach can fulfill linear array pattern synthesis with constrains such as steering a beam in a given direction, null steering, and sidelobe level suppression. Moreover, similar performances of the adaptive synthesis method based on several iterative computations can be achieved only with analytical calculation by this method.
