MitM Radar Defense
Spoofed ISAC Echo Rejection Filters
Signal processing filters that detect and discard counterfeit radar echoes injected by malicious electronic warfare devices attempting to spoof radar targets.
Technical Explanation
Because 6G base stations act as radar sensors (ISAC), hostile adversaries can deploy electronic warfare repeaters that capture transmitted communication waves, modify them, and broadcast fake echoes to create phantom obstacles, ghost vehicles, or false collision warnings in autonomous traffic systems. MitM Radar Defense embeds dynamic, unpredictable cryptographic watermarks into transmitted communication waveforms, allowing radar receivers to instantly verify the authenticity of every reflected echo.
Key Functions
- Cryptographic watermarking of transmitted ISAC waveforms to authenticate reflections
- Detecting and filtering out synthesized false radar echoes and phantom ghost targets
- Protecting autonomous vehicle and drone traffic management systems from electronic spoofing
- Direction-of-arrival consistency checking verifying that echoes obey physical ray geometry
- High resilience against electronic warfare digital radio frequency memory (DRFM) jammers
