Résumé
Non-linear RADAR are used to detectcommunicating electronic systems in electromagneticenvironments. The exploitation of the non-linear (NL)characteristics of the targets is necessary to achieve this.In our case, we collect the third order intermodulation productIM3 of the RF systems in order to detect them. A multi-bandarchitecture of our RADAR is presented as well as the associatedextended protocols included the use of a new method ofdetecting targets. Finally, we introduce a simulation model thatwe developed to predict the performances of our RADAR.
