    This paper presents an IEEE 802.15.4z-compliant impulse radio ultra-wideband (IR-UWB) radar system for gesture detection. The presented IR-UWB radar system detects whether one of 12 predefined gestures has been performed by a person sitting on the passenger seat of a vehicle. The defined gestures include various hand movements, e.g., swiping left-right, or rotating the hand clock-wise. For the ...

    This paper demonstrates an IEEE 802.15.4z compliant Impulse Radio Ultra-Wideband (IR-UWB) radar system for in-cabin monitoring for automotive applications. The presented system demonstrates three in-cabin use cases running in real-time: occupancy detection, breathing rate estimation, and gesture detection. The IR-UWB radar system detects occupancy and estimates the breathing rates of persons ...

    In this paper, we propose a human gesture recognition algorithm using impulse radio ultra-wideband (IR-UWB) radar. The radar signal is transmitted into a three dimensional space, however, the received signal is only expressed in one dimensional. Therefore, it is difficult to classify 3-D gestures by analyzing specific features, such as power, peak value, index of peak value, and other values ...

    A. Ultra-Wideband (IEEE802.15.4a - HRP) In 2007, the IEEE 802.15.4a task group [17] finalized a first standard for UWB systems based on the HRP (high rate pulse) PHY. Frame structure and PHY settings. An IEEE802.15.4a-compliant UWB frame is split into a synchronization header (SHR) and a data portion (DP), as shown in Fig. 1. The SHR is ...
  6. towards an impulse radio based secure ranging and localization technology, built upon the IEEE 802.15.4a and IEEE 802.15.4z standards. Over the last decade, 802.15.4a based solutions have started to see in-creased adoption within high accuracy indoor real-time locating system (RTLS) applications, while in the last
