Sentinel-1 works by illuminating a 250km long and 5km wide swath of land below the satellite with a pulse of C-band radio waves (shown as the red triangle). If interference is detected, its source (depicted as a yellow dot above) will be located somewhere within this swath.
Other military radars that operate on the same C-band frequency include naval radars such as the Japanese FCS-3, the Chinese Type-381 and the Russian S-400 Surface to Air Missile system. All should be detectable when switched on and in view of Sentinel-1.
