This article discusses methods for processing interferometric SAR and multispectral optical data. The main stages of satellite radar and optical data processing are considered, including data preprocessing, geometric co-registration of radar images, interferogram generation, phase unwrapping, reduction of topographic and atmospheric effects, detection of ground deformation, radiometric and geometric processing of optical images, and calculation of spectral indices. The possibilities of using Sentinel-1 interferometric SAR and Sentinel-2 multispectral optical data are analyzed. The combined processing of radar and optical data provides opportunities to detect ground deformation, assess land cover and natural characteristics of an area, and improve the comprehensive monitoring of hazardous geological processes.
