A Systematic Evaluation of the XeThru X4 Ultra-Wideband Radar Behavior.

Ultra-wide band radar systems have gained even more popularity as an emerging technology in health-related research and particularly in the context of ambient intelligence for activity recognition inside smart environments. Indeed, recent technological advances have facilitated their implementation on smaller SoC at lower cost. However, observed practical behaviors not always meet theoretical prediction. Therefore, this paper presents an empirical evaluation of Novelda XeThru X4-based IR-UWB radars behavior. To this end, several experiments were conducted to provide insightful analyses to consider while exploiting such recent technology. We believe that these assessments will benefit to academic researchers by guiding their implementation choices to design new robust activity recognition systems. [ABSTRACT FROM AUTHOR]
