A Viewpoint of Time Variant Dielectric Effect in Vital Sign Detection Using Microwave Radar

摘要：

Through theoretical analysis and data examinations for a continuous microwave radar system, it is pointed out that there are some inconsistencies when using Doppler radar theory to explain the mechanism of vital sign detection. Meanwhile a time variant dielectric hypothesis viewpoint based on bioelectrical effects is presented, and a simple system model is established. Comparing to the traditional Doppler radar theory explanation, this viewpoint is more reasonable.
