说明：  该算法包含极大似然估计的梯度算法和快速ica算法，已经调试成功过，调试时注意所给信号x是行向量还是列向量(The algorithm contains the maximum likelihood estimation of the gradient method and fast ica algorithm, has been debugged, debugging attention given signal x is a row vector or column vector)

关于蝶形宽带微带天线的设计 索引：蝶形宽带微带天线. 设计方案 排列效率 摘要：现在提出一种基于绝缘体衬底的有限长度的宽带微带天线的设计方法。这种方法快速、对计算精度要求较低，是建立在一蝶形天线进行二等分而形成的两个梯形天线的 。首先设计出单边的梯形部分，然后制作出相同的另一部分并在其顶点处将其连接。与理论计算相比在X波段上实验测量表现得很好。其有效带宽达到10.6％ (One approach to an antenna book starts with a discussion of how antennas radiate. Beginning with Maxwell’s equations, we derive electromagnetic waves. After that lengthy discussion, which contains a lot of mathematics, we discuss how these waves excite currents on conductors. The second half of the story is that currents radiate and produce electromagnetic waves. You may already have studied that subject, or if you wish to further your background, consult books on electromagnetics.The study of electromagnetics gives insight into the mathematics describing antenna radiation and provides the rigor to prevent mistakes. We skip the discussion of those equations and move directly to practical aspects.)

i need the matlab coding for image fusion using different types of techniques . so, i need the particular coding your file. i need different types pf transform like IHS,PCA, DCT, and brovey transform.

雷达信号检测和信息提取:根据雷达接收到的信号检查是否含有目标反射回波，并从反射回波中测出有关目标状态的数据。信号是信息的载体，信息是信号的内容。雷达工程界习惯于把雷达信号检测和信息提取的具体实施称为雷达信号处理，并把这种处理与测出的数据的处理合称为雷达信息处理。技术科学界最初把采用数理统计工具解决这一类信息处理的理论问题称为检测理论，后又称为检测与估计(Radar signal detection and information extraction, according to the received radar signal check whether contain the target echo, and measure the echo data on target state.Signal is the carrier of information, the content of the information is a signal.Radar engineering is used to the specific implementation of the radar signal detection and information extraction called radar signal processing, and the processing and the processing of measured data as radar information processing.Technology of the scientific community initially put the use of mathematical statistics tools to solve this problem is known as a kind of information processing theory testing theory, also known as the detection and estimation)
