Linear Non-Equidistant Antenna Arrays

Chapter
Part of the Astrophysics and Space Science Library book series (ASSL, volume 268)

Abstract

This chapter is concerned with phased linear antenna arrays. All the elements of a linear array are spaced along a straight line (denote it as X — axis), so that Eq. (5.1) takes the form
$$f(l) = \sum\limits_{j = 1}^k {{c_j}} {\kern 1pt} \exp [2\pi i/\lambda \cdot (l - {l_0}){x_j}],{\kern 1pt} {x_1} = 0,{\kern 1pt} {x_k} = L$$
(6.1)
Given values of L and k, the problem of the construction of such an array comes to the choise of the element coordinates and weights which provide the minimum SL. In view of non-linearity and multi-extremality of this problem, its solution for k > 20 is too complicated, therefore several simplifying suggestions are made.
