The monograph presents the results of scientific research obtained by the authors - employees of the Research Institute of Aerospace Image Processing of the Ryazan State Radio Engineering University - in the course of work on the creation of means for ground-based processing of information from space systems of Earth radar observation. These results are new models, algorithms and technologies for primary, geometric and interferometric processing of space radar information. For the first time in the domestic literature, a wide review and comparative analysis of existing foreign technologies for primary, polarimetric and interferometric processing of radar data is provided.
