The small-scale artifacts generated by aliasing noise existing everywhere in an image
bring difficulties to some applications
such as target identification.Eliminating aliasing noise algorithm used in push-broom CCD image gathering system is derived and optimized.The strategies for CCD push-broom scanning and the novel methods for data processing are proposed.Aliasings in image are eliminated although CCD array can only move in one direction in remote sensing imaging system.The relative scan error must be less than 1/4 of CCD interval.The results of images processing experiments verify the validity of aliasing noise processing methods.
