在matlab上实现灰度共生矩阵的生成以及特征的提取(GLCM texture matlab)

FM demodulation signal

从介绍功率谱的估计的理论基础入手，分析经典谱估计和现代谱估计，以及在Matlab中的实现方法。(Introduced the power spectrum from the estimated theoretical basics, analysis of classic and modern spectral estimation spectral estimation, as well as the realization of Matlab.)

说明：   二维空间中的多边形逼近算法 确定三个顶点a，b，c并且其函数值按从小到大排列( Two-dimensional space of polygons in the approximation algorithm)

说明：  用于根据 三维 数据 点 计算平面度 的 matlab 程序。(According to data points for three-dimensional flatness of matlab calculation procedures.)

时间序列ARMA建模实例，包含对数据的平稳性检验、白噪声检验及依据ARMA模型的预测。(ARMA time series modeling examples, including the data stationary test, white noise testing and forecasting based on ARMA model.)

说明：  matlab计算二阶微分方程，有详细介绍过程，适合新手上路。(Matlab calculates the second-order differential equation, has a detailed description of the process, suitable for novices on the road.)

说明：  雷达数据处理程序，对于虚假目标的产生，采用在距离、方位角、俯仰角三个方面分别产生随机噪声。(There are six tracks in the main function, which are straight track 1, circular track, straight track 2, straight track 3, figure 8 Track and ellipse track. The generation method is to first generate the track in rectangular coordinate system according to the motion equations of various tracks, in which 8-word track and ellipse track are generated by calling the functions of eighttrack and ellipsetrack respectively, and then use the coordinate system transformation to convert the value of rectangular coordinate system into the value of polar coordinate system, that is, distance, azimuth and pitch angle. It is worth noting that the image should be considered in the transformation process)
