摘要：
Ultra-Wide Bandwidth (UWB) radar can probably detect an intruder by virtue of his/her heartbeat. Ordinarily used for detection of buried objects, UWB radar can measure the Doppler frequency shift caused by the radar impinging on blood pumped in the heart to infer the presence of a human in situations where other sensors cannot, or to supplement other sensors. The heart is divided into four chambers. Two are called ventricles. They contract thereby ejecting blood at high speed. Detection improves as the intruder becomes increasingly agitated or runs. Pumping action of the heart is modeled mathematically.
