PHASE THEORY OF ANTENNA BEAM
-
摘要: 本文簡要地回顧了傳統(tǒng)上對天線的要求,并以實例說明隨著近代科學(xué)技術(shù)發(fā)展的需要,天線波束的相位特性應(yīng)該引起重視和研究,在此背景下本文試圖將天線波束相位和孔徑電流分布等有關(guān)問題系統(tǒng)化,在前人工作的基礎(chǔ)上,總結(jié)并討論了關(guān)于相位參考點、不同相位參考點的天線方向圖的變換關(guān)系、方向圖的零點電平和相鄰波束間的相位差,線陣電流分布的分解;提出并從理論上證明了天線同相波束的普遍條件和連續(xù)線陣的對稱波束條件。歸納為幾個定理,并將這些論述統(tǒng)稱為天線波束相位理論。

Abstract: The traditional requirements for the antenna are reviewed. Under such background and on the basis of previous work, the subjects concerning the phase of antenna beam and the current distribution of antenna aperture, such as the phase reference point, the trans-formation relationship of the far field patterns corresponding to different phase reference points of an antenna, the null level and phase difference between the adjacent beams, and the resolution of current distribution of the linear array are systematized and discussed. The general condition of the beam in phase and the condition of the symmetric beam of a continuous linear array are given and proved theoretically. Some theorems are proposed, and the whole is termed the phase theory of antenna beam. -
