Stepped-FM UWB Home Security Sensor Using Tracking Filter

This paper presents a human detection with tracking filter for a stepped-FM UWB home security sensor. UWB sensor has attracted considerable attention because of its detecting human body in a home. Although it offers high raging accuracy for people in motion in a room, it should be difficult to cover a house through walls. Therefore, we present a human detection with tracking filter using a stepped-FM UWB radio which can estimate the human motion trajectory. The measurements were conducted for two scenarios inside a typical four room apartment house using our fabricated sensor system.
