Shared aperture jamming
Webb1 mars 2016 · A passive-jamming reflector can be designed with rotating or vibrating motions to superimpose ghost targets on the real scene, which needs to be protected from being imaged by SAR. This passive-jamming method is termed as m-D jamming and the ghost targets are named as the jamming strip [ 21 - 23 ]. Webb15 nov. 2024 · The aperture of the array is 200 mm × 200 mm, which is commonly used in the adaptive anti-jamming antenna system. Whereas in the simulation, we place the BDS radiation element at the center of a 100 mm × 100 mm ground plane at first. After we obtain an optimal result, we place the element at the center of a quarter of the 200 mm × …
