Abstract
The design and development of a personnel radar detection system based on the identification of micro-Doppler shifts from heartbeat motion is presented here. The paper reviews the phenomenon of micro-Doppler effects measured in radar systems, and describes a specific detection scheme based on this theory. The detection performance for a general radar system is described, and specific results for a prototype system are then presented and analyzed in support of the theory. The signal processing techniques used to estimate heartbeat rates are described in detail and experimental results are provided for actual human targets demonstrating the effectiveness of the system design. The results focus on the detection capability as a function of standoff range to provide a real-world performance measure of the system.Keywords
