EventRadar: Long-Range Visual UAV Discovery through Spatiotemporal Event Sensing
Researchers have developed EventRadar, a novel system for detecting unmanned aerial vehicles (UAVs) at long ranges using event cameras. This system leverages the temporal periodicity of propeller-induced motion, a cue that remains visible even when visual appearance degrades at distances up to 1500 meters. EventRadar fuses scanning events with IMU pose data to create a scene memory, distinguishing transient targets from background clutter, and employs a specialized algorithm to recover harmonic evidence of UAV activity. In tests, the system achieved high detection accuracy, significantly reducing false negatives and demonstrating real-time feasibility. AI
