摘要

宽带室内信道的时延分布会随着入侵者等物理变化而波动。为了保护房屋而不是房间,本文研究了利用2.4GHz (ISMband)宽带无线电进行人体检测的方法,因为该无线电具有高距离分辨率,可以穿透墙壁,并且在时域上可以区分来自人体的反射路径。在一个场景下,有人闯入一个有四个房间的典型房子并四处走动,实验调查了这种有用性。

Home security sensor using 2.4GHz ISM band
Delay profile of wideband indoor channel fluctuates for a physical change such as intruder. This paper investigates a human body detection using the wideband radio at 2.4GHz (ISMband) in order to protect a house, not a room, because the radio with high range resolution can penetrate into the inner walls and also the reflected paths from human body are discriminated in time domain. The usefulness is experimentally investigated under a scenario which someone intrudes into a typical house with four rooms and walks around.
