摘　　要：雷达阵列天线常涉及方向图综合,而天线阵综合常是利用优化算法优化幅相及阵元间距等参数的过程。提出一种基于特征值滤波器方法的阵列天线波束赋形综合方法。该方法在最小二乘误差准则下,将阵列复值权矢量求解问题转化为一个求解复Hermitian矩阵的最小特征值对应的特征向量的问题。设计中还可方便地加入零陷约束等线性约束。通过实例设计验证了提出方法的有效性。Radiation pattern synthesis is usually required in radar antenna array design, while antenna array synthesis usually involves optimization of characteristics such as the amplitudes and phases of the radiating elements and the distances between the elements by use of optimization algorithm.In this paper,an eigenvalue filter method is proposed for phased array beam shaping synthesis. Under least-square error criterion, the array weights are obtained by computation of an eigenvector of an appropriate complex, Hermitian symmetric,and positive-definite matrix.Several design examples are used to illustrate the effectiveness of the proposed approach.
