摘要: 由于多波束天線系統(tǒng)在近代通信中占有愈來愈重要的地位,本文從陣輻射空間基本性質(zhì)出發(fā),將最小均方自適應(yīng)技術(shù)擴(kuò)展應(yīng)用于多波束天線系統(tǒng),從而提出自適應(yīng)多波束三維陣天線課題。它包括:自適應(yīng)三維陣系統(tǒng)輻射圖型表達(dá)式;瞬態(tài)陣輻射圖型生成過程;陣系統(tǒng)輸出信/噪比表達(dá)式;自適應(yīng)多波束網(wǎng)絡(luò)的構(gòu)成。

Abstract: The multi-beam antenna systems become increasingly important in moden communi-cations, so in this paper, according to the properties of array radiation space, the LMS adaptive techniques are generalized for multi-beam antenna systems. And the follow-ing theoretical aspects of the said arrays are discussed: the radiation pattern of three-dimensional adaptive arrays, the evolution of radiation pattern of the adaptive arrays, the signal-to-noise ratio of the array system output, and the structure of the adaptive multi-beam networks. -
