板波的频散曲线

这是matlab课本的对应的习题解答 用于学习和交流只用 请勿用做非法用途(this is the answer of some question in the book matlab,only for study and communication )

也是自适应的波束形成，有中文注解,好好看，应该能看懂的(adaptive beam forming)

求瞬时频率必不可少，MATLAB系统不自带的，下载后放在MATLAB到toolbox，然后在EMD文件夹下，更新MATLAB路径即可。运行emd即可出现频谱分析图。(It is necessary to find the instantaneous frequency. The MATLAB system does not come with it. After downloading, it is placed in the MATLAB to toolbox. Then, under the EMD folder, the MATLAB path can be updated. The spectrum analysis diagram can appear when EMD is run.)

说明：  该存储库包含雷达合成孔径雷达成像的软件模拟，包括线性调频（LFM，合成孔径雷达成像中使用的基本信号）、简单的点目标合成孔径雷达成像（您可以了解合成孔径雷达是如何工作的）以及实际数据处理（原始数据处理后获得图像）。(This repository contains the software simulation of Radar SAR imaging,including the Linear Frequency Modulation(LFM, basic signal employed in SAR imaging), the simple SAR imaging with Dots Targets(you may learn how SAR works), and finally the real data processing( An image is obtained after the processing of raw data.)

雅克比迭代求解线性方程组课设,阐述了负荷预测的应用研究,主要为数据分析和统计，GSM中GMSK调制信号的产生，能量熵的计算，最小二乘回归分析算法。

雅克比迭代求解线性方程组课设,有较好的参考价值，相参脉冲串复调制信号，关于超声波倒车雷达测距的，阵列信号处理的高分辨率估计，采用加权网络中节点强度和权重都是幂率分布的模型。

Minimizes the bandwidth of a matrix in form of decreasing squares.

核磁共振方法是一项尖端技术，在物理学和医学等领域有着较普遍的应用。 其无损性和高分辨率的特点是这项技术最大的优势。而利用核磁共振方法来找水 是其在地学中应用的一个新领域，为地球物理方法提供了新的思路。(NMR is a cutting-edge technology, medicine and other fields in physics and has more general application. The high-resolution non-destructive and are characterized by the biggest advantage of this technology. The use of NMR to come to learn that water is applied in a new area for geophysical methods to provide a new way of thinking.)

Monte Carlo nonchronological Generation

本文是关于图像叠加处理的matlab程序，其中包含了图像位置改变和透明度的变化。(Superimposed image processing, the image position on transparency and the like. .)
