The Study of UWB Radar Life-Detection for Searching Human Subjects

This paper gives a simple introduction for the UWB radar and its definition. The principle of the radar will be a represent in details. Excellent materials penetration is a fundamental advantage to UWB radar. This point can be used to detect the signals of life without touching anyone. Since the human body's chest wall movement can be assumed a simple harmonic motion, the chaos theory can be applied to detect the low-frequency signal. There are several advantages including high resolution and accuracy. This method is simpler compared with the traditional means.
