Description: 波束图定义为当阵列输入为平面波时，阵列输出与平面波入射角的关系。阵列天线的方向图是全方向的，但阵列的输出经过加权求和后，却可以使阵列接受的方向增益聚集在一个方向上，相当于形成一个波束，-The wave beam chart defines to work as when array input for plane wave, array output and plane wave incidence angle relations. Array antennas s directional diagram is entire direction, but array output after weighting summation, actually may cause the directive gain which the array accepts to gather in a direction, is equal in forms wave beam,

Description: 本文给出了一种利用幅相加权对阵列天线进行全局优化的方法。为了使天线的辐射波束形成给定的
方向图，采用联合应用DFP和BFGS公式的变度量算法对阵列天线各单元的馈电幅度和相位分布进行优化，
通过C++语言编程计算实现，从而使得优化后的阵列天线主波束形状能够与预给波束形状相吻合，达到设计
要求。全局优化是本文的特色，它弥补了局部优化结果的精确度依赖于初始值的缺点，因而得以保证通过优
化得到的天线主波束与给定波束的主瓣相吻合，副瓣也得到有效控制。该方法具有快速收敛，计算量小等优
点，是一种解决阵列天线波束赋形问题的有效方法。 -In this paper, the amplitude and phase weighted array antennas for global optimization method. Order to make the antenna radiation beam to form a given pattern, using the combination of DFP and BFGS formula variable metric algorithm to optimize the amplitude and phase distribution of each cell of the array antenna feed, calculated through C++ language programming to achieve, which makes optimization array antenna main beam shape is consistent with the pre-to the beam shape to meet the design requirements. Global optimization is a feature of this article, it makes up for the shortcomings of the accuracy of the local optimization results depend on the initial value, and thus can be guaranteed through the optimization of the antenna main beam to coincide with the main lobe of a given beam, sidelobes also been effectively controlled . The method has fast convergence of computing and small volume, is a solution to the array antenna beamforming.

Description: 电子扫描阵列(ESAS)提供了可命令的、灵活的高增益波束的能力，这对于诸如雷达、天气监视和成像的应用是有利的。与需要用于操纵阵列波束的万向架的反射器天线相比，ESAS在空间中电子地扫描阵列波束而没有阵列的物理移动。与反射器的毫秒相比，用ESA扫描光束可以在微秒量级上执行。这使得除了灵活性之外，还能够增加扫描速率，以命令阵列束在空间中的位置用于定制的操作模式。(Electronically scanned arrays provide the capability of commandable,agile,high-gain beams,which is advantageous for applications such as radar,weather surveillance,and imaging.In contrast to reflector antennas,which require a gimbal for steering the array beam,ESAs electronically scan the array beam in space without physical movement of the array.Scanning the beam with an ESA can be performed on the order of microseconds as opposed to milliseconds for a reflector.)
