  • After briefly interoducing the characteristics of 1/f noise in millimeter wave focal plane array detectors, the paper analyses the relation of the wavelet transform and 1/f noise in detail and suggests the fashion of decorrelating 1/f noise using the wavelet transform., also deduces the relative expressions. The results of computer simulation show the good effect.
