… In this study, the X4 (IR-UWB) present a wavelength 10 times larger than the IWR1843 (FMCW)
and therefore, in addition to their operation mode differences, the quality of the …

… time response where they can transmit and receive UWB … certain distance away from the
antennas for this radar system … (Figure 2), the distance between the target and the antennas …

… UWB radar system is constantly increasing due to its ability to provide precise images of
hidden targets in a short period of time. … The aim of this work is to design a novel IR-UWB radar …

… time delay ( t = 3 ~ 7 ns) by an object in the detection range of interest. To prevent erroneous
detections, the receiver is turned on only when the reflected pulse from an object exists in …

… (as in the case of IR UWB) which makes the device … time delay between the transmitted
pulse and the received one is proportional to the distance R0 (range) from the target to the radar…

… count the number of breaths they took over a period of 180 seconds. We have also collected
… of columns in each dataset that present a propagation time that is larger than tmax = 1.5 …

… The amplitude of the R(t) is represented by a 2-D CIR matrix, characterized by two dimensions:
fast-time and slowtime. IR-UWB radar utilizes the time-domain positions of the impulses …

… In order not to lose any data during the actual articulation, we apply a 0.2 s margin to the
beginning time and a 0.1 s margin to the end time. Thus, the data between 0.27 s and 1.38 s are …

… In this manner, the two devices were synchronized in time by finding the section where the
… IR-UWB appear flat at the same time. Moreover, we could synchronize the devices in time by …

… -speed time domain analog-to-digital con- verter (ADC) customized for impulse radio ultra-wideband
(IR-UWB) radars is … It adopts a power efficient architecture combining time domain …
