Abstract

This letter presents a fast exponential analysis and variable projection method to reduce the number of elements in linear phased arrays. The numerical examples given in this work demonstrate a reduction of approximately 20% or 10% in the number of elements, with only a slight decrease in directivity of 0.63 dBi observed for a scan range of

$[-45^\circ,45^\circ ]$

. Compared with the combined matrix pencil and Tabu search algorithm, the proposed technique converges in fewer iterations and exhibits

$\approx {\text{5}}$

dB reduction in maximum sidelobe level.

基于快速指数分析和变投影的线阵综合方法

本文提出了一种快速指数分析和可变投影方法，以减少线性相控阵中元素的数量。本文给出的数值例子表明，在$[-45^\circ,45^\circ]$的扫描范围内，元件数量减少了大约20%或10%，指向性仅略有下降0.63 dBi。与矩阵铅笔和禁忌搜索相结合的算法相比，该算法迭代次数更少，最大旁瓣电平降低$\ \约{\text{5}}$ dB。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
