阿贝成像与空间滤波，利用傅里叶变换产生频谱，对频谱进行滤波，然后进行傅里叶逆变换-Abbe imaging with spatial filtering, the use of Fourier transform generates spectral filtering of the spectrum, and then inverse Fourier transform

通过对数据滤波来进行对静态效应的消噪过程，本代码使用了空间滤波、组合滤波、中值滤波等方法进行对比。-Through data filtering to eliminate noise of static effects of the process, the code uses the spatial filtering, a combination of filtering, median filtering and other methods were compared.

气象上这是一个空间滤波的程序，在这个程序里面我们利用ncep的2.5*2.5*17的日平均位势高度数据 !目的是对位势高度的空间波动进行空间谐波滤波，得到空间行星尺度波和天气尺度波-This is a spatial filter process, which we use in this program ncep daily average bit 2.5* 2.5* 17 potential height data ! Aim is a high degree of spatial
