Intelligent Recognition of Chirp Radar Deceptive Jamming Based on Multi-Pulse Information Fusion
The perception of jamming types is very important for protecting our radar in complex electromagnetic environments. Radar active deceptive jamming based on digital radio frequency memory (DRFM) has a high coherence with the target echo, which confuses ...

Security against jamming and noise exclusion in imaging [PDF]
We describe a protocol by which an imaging system could be protected against jamming by a malevolent party. Our protocol not only allows recognition of the jamming, but also allows for the recovery of the true image from the jammed one.
