圆形阵列特征矢量综合法及其在自适应DBF中的应用

Circular Array Synthesis Using Eigenvector Techniques and Its Applications in Adaptive DBF

本文给出了圆形阵列的一种方向图综合方法——特征矢量综合法。该方法的综合途径是,通过找出一权矢量,使圆形阵列在空域[π,π]上的平均功率响应在单位模约束下最小化。数值结果表明该方法对于降低圆形阵列天线旁瓣是十分有效的。文中还通过数值例子说明了特征矢量综合法在自适应数字波速形成(DBF)算法中的应用效果。

A new technique for circular array synthesis is presented in this paper. The appronch taken is to find a weight vector which minimizes the average integrated power response of the array in the spatial region[—π,π]. Numerical results show that it is efficient to reduce the sidelobe level of circular array antenna and application examples of the new synthesis technique in adaptive DBF are also presented.
