生物雷达信号处理方法研究进展

Research progress of signal processing method for bioradar

生物雷达是雷达技术与生物医学工程技术相融合、可在较远距离探测生命信号的特殊雷达，是近年来国外提出的一种新概念雷达。该技术可用于生命体征探测以及非接触临床监护领域。生物医学信号处理方法是该技术得以实现的重要条件。生物雷达信号容易受到检测对象及环境的干扰，特别是呼吸运动回波信号较强，对心搏信号产生混合干扰，使其无法独立检出。因此大量信号处理方法运用在该技术的各个方面。介绍了生物雷达技术进展，以及当前主流信号处理方法的应用情况。

Bioradar is based on the integration of theory of radar and bio-mcdical engineering, which can detect the life-parameters in farther distance. It is new concept radar presented by foreign experts. The technology can be widely used in detection of lifeform signal and non-contact clinical monitoring. Biomedical signal processing method is the premise that the technology can be realized. The signals can be interfered by the environmental factors, breath motion and so on, especially the influences of breath motion which can not be solved by average methods. A large number of signal processing methods are used in various aspects of the technology. This review introduces the progress of bioradar technology and the application of the current signal processing methods in the field.
