Requirements are especially challenging for person detection [1]: a bandwidth higher than 1.5GHz is needed to achieve finer than 10cm depth resolution. Wide field of view combined with high angular resolution are also needed, which at mm-Waves translate into large and powerhungry antenna arrays. In classical FMCW radars [2-6], when bandwidth requirements exceed 1GHz, depth resolution is eventually limited by the linearity of the frequency slope of the FM PLL. This paper describes a phase-modulated Continuous-Wave (CW) Radar TX that operates in the 79GHz band. With a sampling rate of 2GS/s and 4GHz RF bandwidth, we target a resolution of 7cm. We rely on a Pseudo-Random-Noise
