在许多应用中，需要恢复信号的高频成分，例如，在雷达和声纳中，可以通过光谱外推获得更高的距离精度；在成像系统中，图像的恢复将提供更高的分辨率。恢复图像的精细细节的能力在天文学、电子显微镜、卫星监视、医学图像处理、遥感等不同领域具有明显的价值。在图像数据压缩应用中。
There are many applications where it is desirable to restore the high frequency components of a signal, for example, in radar and sonar, greater range accuracy can be obtained by spectral extrapolation, In imaging systems, the restoration of an image will provide increased resolution, The ability to restore the fine details of an image is of obvious value in such diverse fields as astronomy, electron microscopy, satelite survailance, medical image processing, remote sensing, and in image data compression applications.
