Abstract
The present disclosure relates to radar decoys, methods for controlling radar decoys and UAVs having a radar decoy. The radar decoy may comprise a passive reflector arranged to reflect radar signals, and a semi-active metasurface configured to have a reflection coefficient with a time-variable complex component. The present disclosure also relates to a method of controlling a semi-active radar metasurface.
Claims21
A radar decoy comprising:
- a passive reflector arranged to reflect radar signals;
- and
- a semi-active metasurface configured to have a reflection coefficient with a time-variable complex component.
A method of controlling a semi-active radar metasurface, the metasurface arranged to have a reflection coefficient with a time-variable complex component, the method comprising:
- applying a time-varying voltage across the metasurface, to thereby generate a time-variable complex component in the reflection coefficient which causes a radar signal reflected from the metasurface to mimic a doppler shift.
