Analysis of imagery interpretability of open sources radar satellite imagery

Abstract

The subject of study were low resolution SAR imagery, provided by Sentinel 1A and 1B, which can be obtained using open sources. Due to the great interest of products, an analysis of the interpretation possibilities of imaging acquired in interferometric wide swath mode and extra wide swath mode were made. Before exploring the possibilities, the proposed methods have been tested to improve the quality of radar images. Depending on the analyst’s needs as well as the polarization channel used, adaptive filters such as Frost, Lee-Sigma, and in some cases Gamma-Map are recommended. However, the use of classification and pseudocolor allows dividing the area of interest into basic fields, such as the urbanized area, water or vegetation. Satisfactory results were also obtained by integrating different polarization bands. The impact of incidence angle of radar beam on photographing the object was also shown.
