Fall Detection Doppler Radar System Based on Time and Spatial Division
This work demonstrates a 2.45-GHz beamswitching Doppler radar system for real-time human fall detection. By utilizing Butler matrixes for beam switching, the system divides the spatial coverage to distinguish different body regions. Combined with time-sequence information, it enables the continuous tracking of human motion, providing more comprehensive data for fall detection and analysis. Experimental results validate the feasibility and reliability of the proposed system.
