摘要

摘要: 生命探测雷达技术是近些年发展起来的一种新型非接触式生命检测技术，其通过对生命体的振动信息进行测量实现生命体检测和定位。由于生命体的振动幅度一般较小，噪声会对生命探测雷达的测量性能造成严重的干扰，而噪声（热噪声和相位噪声）对此类雷达测量性能的影响目前尚无有效的评价指标。针对这一问题，该文通过建模分析定义了生命探测雷达的微多普勒测量灵敏度并提出了分析该指标的新方法，有效地解决了生命探测雷达测量性能无法定量分析的问题。最后通过仿真给出了给定系统在不同距离的测振性能曲线。

Abstract: In recent years, a new non-contact life detecting device has been developed, known as life-detection radar, which can measure bodily movement and locate human subjects. Typically, the amplitude of the vibration being measured is quite small, so the measurement is easily contaminated by noise in the radar system. To date, there is no effective index for judging the influence of noise on the vibration measurements in this radar system. To solve this problem, in this paper, we define the micro-Doppler measurement sensitivity to analyze the influence of noise on the measurement. We then perform a simulation to generate a performance curve for the radar system.
