firstly, the basic theories and parameters of antenna arrays is studied, and the conception of arrays synthesis is given 本文首先介绍了阵列天线的基本理论和各项技术指标,给出了阵列综合的概念。
in this dissertation, the key techniques in distributed arrays synthesis are studied in detail, and the tolerance is distributed arrays analyzed 本文深入研究了分布式阵列综合的关键技术,并对其进行了容差分析。
the method uses both linearly constraints and quadratic pattern constraints to control the beam pattern, which is used in arbitrary array synthesis . it is simple effective and feasible 此算法同时应用了线性约束和二次约束来控制波束特征,适用于任意阵列的综合,算法简单,计算效率高。
secondly, the dissertations gives two array synthesis methods with aspect to circular array to cancel the ionosphere clutter, one is the circular max directivity synthesis method under condition of vertical pattern zero point restriction, the other is the circular max directivity synthesis method under condition of vertical pattern zero point restriction and efficiency restriction 然后为了对消电离层干扰,本文给出了两种圆阵列最大方向性综合方法,第一种是在垂直面方向图零点约束下的综合方法,第二种是在垂直面零点约束和效率约束下的综合方法。
