说明：  关于SAR成像的matlab程序，感觉还可以(Matlab on the SAR imaging process can feel)

Quadrature amplitude modulation (QAM) is both an analog and a digital modulation scheme. It conveys two analog message signals, or two digital bit streams, by changing (modulating) the amplitudes of two carrier waves, using the amplitude-shift keying (ASK) digital modulation scheme or amplitude modulation (AM) analog modulation scheme.

这是关于PCA主成分分析降维，文件夹里有.mat格式的数据文件，里面数据可供测试PCA降维使用。(This is about PCA principal component analysis dimension reduction, folder. Mat data file format, data available for test use PCA dimensionality reduction.)

说明：  matlab程序绘制世界地图，这是一个与etopo类似的地形绘制包，很清晰(Matlab program to map the world, this is a similar to etopo terrain mapping package, very clear)
