Novel Phase Noise Measurement for FMCW Radar Waveform

This study presents a method for measuring phase noise in Frequency Modulated Continuous Wave (FMCW) radar systems, primarily used in automotive radars. The method involves capturing the FMCW signal, removing the linearly changing frequency, and measuring the phase noise within the FMCW signal. The proposed method was validated using a 77GHz FMCW signal, and the results were compared with those obtained using a phase noise analyzer. Consequently, the proposed method accurately measures phase noise in FMCW radar systems, providing significant insights for analysis radar system performance.
