Description: 单脉冲和差波束测角程序。
此程序实现了线阵8阵元的和差波束测角，利用全阵同时形成两个波束，形成和差波束，随着测量角度的增大其误差也逐渐增大，这是由于这种方法的近似所致和波束扫描时变胖-Single-pulse and beam deviation angle measuring procedures. This program implements linear 8-element array and differential beam angle measurement, using the whole array at the same time to form two beams, beam forming and poor, with the measurement of the angle increases the error also increases, which is a result of this approach approximate due to fat, and beam scan

Description: 这是一个简单的FFT为无电位1 +1 +1 Ð 薛定谔方程的光束传播方法。如果该软件灵活，允许引入的术语（如果是极少数需要包括色散效应高阶导数）。例如，如果一个人渴望解决的一个方程的形式：
（四/ dz的+ Ð ^ 2/dx ^ 2 - 0.25 * Ð ^ 3/dx ^ 3）== 0 Ÿ
它可以解决使用以下代码：
Ž = linspace（0,1,512）
x = linspace（-5,5,1024）
psi0 =进出口（- x的。^ 2）
Ð = D_lateral1D（十，2）-0.25 * D_lateral1D（十，3）
字段= LinearBPM（psi0，有D，Z）
凡D_lateral1D是一个函数，提供“取代”的微分算子。
这个函数是在一个非线性的BPM，我曾对（分步，谱方法等），将提交给我，当我完成他们的文件和组织功能更复杂的设置非常初期阶段。
-This is a simple FFT based beam propagation method for potential-free 1+1+1D Schrodinger equation. The software if flexible and allows to introduce high-order derivatives in the term (very handful if is needed to include dispersion effects). For example, if one desires to solve an equation in the form:
(d/dz+ d^2/dx^2- 0.25*d^3/dx^3)Y == 0
It can be solved using the following code:
z=linspace(0,1,512)
x=linspace(-5,5,1024)
psi0=exp(-x.^2)
D=D_lateral1D(x,2)-0.25*D_lateral1D(x,3)
field=LinearBPM(psi0,D,z)
Where D_lateral1D is a provided function that "replaces" the derivative operator.
This function is a very early stage in a more complex set of non-linear BPM functions that I have made (split-step, spectral methods, etc.) and I will submit them when I finish their documentation and organization.
Sorry for my English, I m eager for your comments.

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

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.
