Urban Radar Clutter Suppression
Spatiotemporal Ground Clutter and Multi-Path Reflection Cancellation for ISAC
Signal processing algorithm that cancels massive static background reflections (from concrete walls and roads) to isolate moving targets in 6G radar.
Technical Explanation
When a 6G base station emits cellular radar waves in a dense urban environment, reflection from stationary skyscrapers, lampposts, and asphalt roads generates overwhelming background interference ('clutter') that blinds radar receivers to small moving targets (like drones or pedestrians). The Urban Radar Clutter Suppression algorithm applies Space-Time Adaptive Processing (STAP) and deep neural autoencoders to cancel static echoes by over 60 dB, revealing low-radar-cross-section moving objects.
Key Functions
- Suppresses overwhelming stationary echoes from skyscrapers and asphalt by >60 dB
- Isolates tiny moving targets like unauthorized drones and crossing pedestrians
- Utilizes Space-Time Adaptive Processing (STAP) tailored for massive antenna arrays
- Enables reliable cellular radar sensing in dense metropolitan street canyons
