老年人想要更独立的生活方式。这带来了一些风险，包括健康状况下降和跌倒造成的重大伤害。研究发现，与跌倒风险相关的一个因素是步态速度的变化。我们的目标是创造一个被动的系统来监测老年人的步态，这样如果步态确实发生了变化，护理人员就可以给出评估。本文将介绍一种使用脉冲多普勒雷达检测行走的方法。在没有脚本的生活环境中，我们能够检测到有效的行走。该系统在白天确实会错过步行，但当步行被检测到时，使用在生活环境中捕获的雷达信号的大型数据库，91.8%的情况下，这些步行实际上是有效的。
Seniors want to live more independent lifestyles. This comes with some risks including dwindling health and major injuries due to falling. A factor that has been studied and seen to have a correlation to fall risk is change in gait speed. Our goal is to create a passive system that monitors the gait of elderly so that assessments can be given by caregivers if gait changes do occur. This paper will cover a method of using pulse-Doppler radar to detect when walks occur. In unscripted living environments, we are able to detect valid walks. The system does miss walks during the day, but when walks are detected, they are actually valid walks 91.8% of the time using a large data base of radar signals captured in living environments.
