This paper presents a radio frequency (RF) CMOS chip and algorithm integrated solution of an Ultra-Wideband (UWB) Impulse-Radio (IR) radar system for human presence detection and tracking. UWB radar can complement other human detection and tracking technologies, as it works well in poor visibility conditions with high time/depth-resolution. UWB radar response provides the complex multipath scattering characteristics in each scan, as well as the high sensitive variation in dynamic observation patterns between scans to pose challenge in designing UWB radar hardware and signal processing algorithm. We develop a UWB IR CMOS human feature detection radar transceiver chip and human presence detection algorithm. Thereafter, we integrated the UWB CMOS radar chip and the algorithm through UWB sensor module, and tested the integrated system in a simple outdoor environment to validate the performance of the integrated system. We present experimental results in which the integrated UWB human detection radar system tracks human and non-human targets, and detects human presence by discerning human from moving non-human objects robustly using human feature extraction and likelihood ratio testing (LRT).
