In this dissertation, what under consideration is the dipole array.

本论文中考虑的都是偶极子阵列，但是对其他型式的单元组成的天线阵的口面分布的实现，本论文的基本思想也有一定的指导作用。

In the end, Chapter 5 has a discuss on the dipole array tacked by a finite reflecting plate.

它们显示在天线阵应用中，调节偶极子单元的长度有可能给系统的设计带来极大的方便。

The hardware of this system consists of antenna array, Doppler direction finder, system controller and display. The software-work mode controller, data processing and angle display.

整套系统的硬件部分包括天线阵、多普勒无线电测向仪、控制电路板和显示电路板，软件部分包括工作模式控制部分、数据处理部分和角度显示部分。

Simulated results show that the directivity and the gain of the array are improved.

模拟结果表明，天线阵的方向性以及增益都得到了加强。

It is easier to fabricate and is easier to integrate with circuit.

论文的写作也不够严谨：1。没有给出天线阵的具体设计过程。2。

Some key techniques using the Method of Moments in the analysis of receiving performance of array are given.

本文给出使用矩量法分析天线阵接收性能时几个关键问题的处理方法。

The number of desired signals is detected by using singular value decomposition. And the array input is transformed into the signal subspace. Orthogonality is derived for the weight vectors in multiple beamforming on this subspace. According to which, an orthogonal constant modulus algorithm is proposed by introducing the orthonormalization procedure into the static least square constant modulus algorithm.

利用奇异值分解确定了用户信号的个数，并把天线阵接收的数据矩阵映射到信号子空间上，进而在该空间中讨论波束形成问题并导出了多用户波束形成的必要条件，依据此条件将正交化过程引入最小二乘恒模算法并提出了正交化恒模算法。

Numerical results verify that the new algorithm has the properties of simple implementation, fast convergence, low computation cost and easy parameter selection.

给出了用该算法对天线阵幅度、相位和幅相综合的数值结果，验证了新算法的有效性。
