Systematically blind, redirect, or feed false information - SBRFFI

 


 

In Electronic Warfare (EW), "closed-loop radio frequency forgery"—more commonly referred to by Thales and defense engineers as closed-loop RF deception or RF cyber-forgery—is an advanced method used to systematically blind, redirect, or feed false information to enemy radar and communication networks. [1, 2] 
Rather than deploying static noise to jam a signal, this architecture utilizes real-time adaptive loops to capture an adversary's incoming transmission, manipulate its metadata or wave characteristics, and retransmit a perfect "forged" copy back to the sender. [2, 3] 
## How the Closed-Loop Forgery Mechanism Works
The workflow relies on a seamless, sub-millisecond feedback loop between the intercepting asset and the target:

   1. Passive Interception & Analysis: [Thales Electronic Warfare systems](https://www.thalesgroup.com/en/solutions-catalogue/defence/electronic-warfare) (such as the SPECTRA suite on combat aircraft or specialized drone payloads) intercept hostile radar or communication waveforms using high-accuracy digital receivers. [4, 5] 
   2. Digital Manipulation (The Forgery): The captured signal is processed via a Digital Radio Frequency Memory (DRFM) device. Rather than merely repeating the signal, internal AI-driven tools extract the precise signature. They modify specific attributes like the Time difference of arrival (TDOA), Doppler shift, or signal strength. [6, 7, 8] 
   3. Adaptive Emitting (The Closed Loop): The system emits the modified, forged RF signal back to the enemy's receivers. It continually measures the enemy's system response (e.g., whether the enemy radar tracks the fake target or changes its Electronic Counter-Countermeasures). The forgery algorithm automatically recalibrates to sustain the deception. [1, 2, 9, 10] 

## Operational Applications

* Radar Spoofing / Range Forgery: Creating realistic "ghost" targets on hostile radar screens. The enemy tracks completely non-existent physical assets while the real friendly platform remains hidden. [2, 11] 
* Communication Impersonation: Forging tactical datalinks or IFF (Identification Friend or Foe) signatures to disrupt enemy battlefield management networks and induce command hesitation. [2, 12] 
* Defeating Smart Guided Weapons: Manipulating the RF guidance seekers of incoming hostile anti-air or anti-ship missiles. The closed loop tricks the missile into recalculating its course toward an empty patch of ocean or sky. [13] 

## Threat Testing via Simulation
Because closed-loop RF forgery relies on highly complex, reactive threat environments, [Thales and test developers](https://www.thalesgroup.com/en/advanced-technologies/simulation) use Closed-Loop EW Simulators. These digital twins model hardware-in-the-loop (HWIL) setups. This allows engineers to safely test how weapon software responds to signal forgery and algorithmic manipulation before deployment. [5, 9, 14, 15, 16] 
Are you researching this concept from an Electronic Counter-Countermeasures (ECCM) perspective to protect networks, or are you looking into specific Thales EW hardware platforms like SPECTRA or CURCO? [1, 4, 5]

Unfortunately, people speaking French feed false information with closed-loop current frequency forgery in wired networks since a longtime, before the internet was deployed, this is why even when you go physically on a server to configure an encrypted link to your remote network, you still can be hijacked and your server can fly over the air all your life without your knowledge. This is urgent to check if multiplexing technologies are not too much fault tolerant...
