Theoretical research and the most rent advances of discrete intensive frequency spectrum zooming analyze and correction methodology was reviewed. According to the numbers of frequency component including in the spectrum, the existing methods are classified into two kinds. One kind of methods deal with spectrum including only two frequency components, the other relate to spectrum including more than three frequency components. The detailed analyses and expatiation are made to account for the basic theory, algorithm, principle, characteristic and application scope. The deficiency of current spectrum zooming methods are discussed, and some possible directions in discrete intensive frequency spectrum zooming analyze and correction domain are tipped.
