N2 - A low-frequency but complex cross-track radiometric variation is found in OMIS hyperspectral images, which can't be corrected well by the general tool as CTIC in ENVI. Therefore a new correction method named as VRadCor is suggested in this paper, and good effect is obtained in some verification examples both for OMIS and HYMAP. It shows that VRadCor adequately considers and uses the spectral features of hyperspectral image on the base of some reasonable supposes. Therefore it can keep the spectral shape well after correction. And furthermore, it can not only obtain both the multiplicative and additive correction factors, but also provide a possibility to locate the optimized base spectra for correcting reference. A contrast between VRadCor and CTIC is also suggested.
