一、引言本文讨论了在宽频带范围内获得指定基阵空间特性的方法。这里将要求有两种通用技术,其中的一种,因它对以后的基阵输出作宽带处理更为合适,我们将对它作较详细的研究。该技术是采用与频率有关的基阵加权(束控)网络为基础的。下列许多情况是关于所希望的空间特性的近似,对产生近似空间图案的、与频率有关的加权函数的近似,以及在实际的网络结构即横向滤波器中实现这些频率函数。
I. INTRODUCTION This paper discusses ways to obtain the spatial characteristics of a given array over a wide range of frequencies. There are two common techniques that will be required here, one of which is more suitable for the broadband processing of the future output of the matrix, which we will study in more detail. The technology is based on a frequency-dependent array-weighted (beam-steering) network. Many of the following are examples of approximations of the desired spatial characteristics, approximation of frequency-dependent weighting functions that produce approximative spatial patterns, and realization of these frequency functions in the actual network structure, transversal filters.
