Аннотация: An alternative instrument distortions correction method for the ETM + scanner on Landsat-7 multispectral satellite images is proposed. The method is based on the filtering application in the field of spatial frequencies using the fast Fourier transform and spectral masks. The visual analysis results of the processed images showed aПоказать полностьюhigh-quality suppression of instrument distortion of the ETM + scanner compared to other methods. Experimental testing of the proposed method on many images confirmed the good repeatability and high stability of the algorithms used. The developed technology can also be successfully used to correct instrumental spatial periodic distortions in archived satellite images obtained using other optical and mechanical scanners. © 2020 International Research Publication House.
