A major drawback of frequency modulated continuous-wave (FMCW) radar systems is the permanent leakage from the transmit into the receive path. Besides leakage within the radar device itself, signal reflections from a fixed object in front of the antennas additionally introduce so-called short-range (SR) leakage. It causes a strong degradation of detection(More)
Estimation of phase noise (PN) has become economically feasible for integration in many of today’s semiconductors. Several contributions propose concepts that obtain a good estimate of the PN’s power spectrum without even requiring a reference oscillator. Differently, in this work we aim to estimate the time domain representation of the residual PN in the(More)
The presence of phase noise (PN) severely deteriorates the sensitivity and range of frequency-modulated continuous wave radar systems. Thus, characterization and continuous monitoring of the PN is indispensable, and its estimation is often employed directly on chip. Although many contributions investigate methods for PN estimation, almost all of them(More)
