UWB technology (3.1 to 10.6GHz) allows new applications for both data communication and sensing (FCC, reference in [1]). Due to their potential in terms of resolution and extremely low level of EIRP spectral density (< -41.3dBm/MHz, see mask in Fig. 2.4.1) [1], UWB radars are very attractive for a large set of civil and military sensing applications, as ground penetrating, surveillance, localization, intra-wall and through-wall detections and biomedical imaging. Moreover, with respect to continuous-wave (CW) radars [2], UWB radar transceivers present a lower circuit complexity since no frequency conversions are required, leading to lower power consumption (PC) for longer battery autonomy. In spite of the implementations of efficient building blocks [3] and especially
