本文针对一些特定用途天线要求较强方向性、较高增益以及方向图能够在空间扫描的问题,首先,介绍了可以完成这些功能的主要天线形式-阵列天线以及相控阵,从其基本理论出发,分析了它们的辐射特性,得出了方向图乘积定理,简单讨论了空间中的波束特性.其次,分析了扫描直线阵列,并用泰勒综合法对直线阵进行综合.接着,在提出以上理论基础上,设计了半波振子阵列天线模型,推导出其近场公式,并利用MATLAB编程计算,对其进行了近场分析,得出阵列天线近场方向图与扫描角及口面距测量面距离的关系.最后对直线阵列的扫描特性进行了比较全面的总结.

For a specific purpose in this article requires strong directional, high gain of the antenna and pattern to scan in space issues, first of all, introduced the main antenna can complete these features form-array antennas and phased array, proceeding from its basic theory, analysis of radiation characteristic of them, came to a directional map product theorem, briefly discuss the beam characteristics of space. Secondly, the analysis of scanning linear array and comprehensive synthesis of linear array by Taylor. Then, on the basis of the above theory, designing model of half-wave dipole antenna array, derive their near-field formulas, and using MATLAB programming calculation, it is a near-field analysis, draw the array antenna near-field pattern scanning angle and distance measurement and distance relationship. Last scan characteristics of linear array to be of a more comprehensive summary.
