天线阵辐射图型强制零点控制,由于对定向干扰抑制的有效性,已成为天线阵辐射图型综合理论中心课题之一。本文围绕着这个课题,对三维天线阵辐射圈的零点控制进行了研究,它包括:用矢量空间方法,分析了多重零点控制的基本关系;根据零点本身的扩展性,引入了零域的概念,提出了多重强制零域的生成方法;导出了多重零点控制辐射图型的分解公式;揭示了由主波束和多个零点强制波束合成多重强制零点辐射图型的基本规律;给出了数值结果并进行了讨论;把这一分解原理与自适应成零天线阵辐射图型进行了类比。
Antenna array radiation pattern forced zero point control, due to the effectiveness of directional interference suppression, has become one of the central topics in the antenna array radiation pattern synthesis theory. This paper focuses on this subject, and studies zero point control of the radiation circle of the three-dimensional antenna array. It includes: using vector space method to analyze the basic relations of multiple zero-point control; introducing the concept of zero-region according to its own scalability, The method of generating multiple forced zero regions is proposed. The decomposition formulas of multiple null control radiation patterns are deduced. The basic laws of multiple forced null radiation patterns synthesized by the main beams and multiple null beams are revealed. Numerical results are given A discussion is made; this principle of decomposition is analogous to the adaptive zero antenna array radiation pattern.
