In the end of November 2023 we could see Radar jamming on Sentinel-1 Radar(SAR) images over Sevastopol.
Sentinel-1 satellites acquire Radar images in C-band frequency and are available on a open source basis. Over Sevastopol on the occupied Crimea Peninsula there are large noise patterns observable on these images on several days in the end of November 2023. Such large and intense noise patterns can only be caused by active jamming. From the resulting pattern we can clearly say that the jamming method was the so called “block” jamming. For this, a transmitter sends out a strong signal in the same – or several frequency bands.
The purpose of this jamming is to disturb and “blind” sensors working in the same frequency bands, like air and sea drones, Radar imaging satellites, or missiles using Radar for orientation and ranging.
23.11.
24.11.
29.11.
When using such a jamming method, we can guess where the emitter or the noise generator was standing when sending out the signal, it is basically the center of the imaged signal:
23.11.
On the 23.11 the noise generator was probably located on a ship, or at the coast:
24.11.
On the 24th there can be seen two different noise centers, both probably on the small road or nearby on the meadows:
29.11.
On the 29th the emitter was probably located at the border of this small village in the south of Crimea:
