Russian radars located in the Rostov region near the border with Ukraine "distorted" the images taken by the European Sentinel-1 satellite, writes Defense Blog.
The publication cites the opinion of experts, according to which we are talking about radar synthesis of the aperture in the C-band — if Sentinel-1 is shooting at a frequency of 5.4 gigahertz with a bandwidth of 100 megahertz, then ground — based radars are somewhere between 5300 and 5500 megahertz.
In November 2020, the Covert Shores blog published "distorted" Sentinel-1 images of Russian warships in the Barents Sea, noting that the publicly available Sentinel-1 images can be used to determine the location of ground or surface radars.
In July of the same year, the Sentinel-2 satellite filmed a rocket launch made in the Barents Sea by a large anti-submarine ship "Severomorsk" of project 1155 "Frigate".
