In: Automotive Radar Seminar, Taiwan (2016) Google Scholar Fölster, F. , 15 (4) (2021), pp. Clustering is usually used as a preprocessing step for classification of the measured data. Michael Parker, in Digital Signal Processing 101 (Second Edition), 2017. Block diagram of the proposed radar signal processing architecture for early detection of automotive obstacles. As one of the core components of Advanced Driver Assistance Systems (ADAS), automotive millimeter-wave radar has become the focus of scholars and manufacturers at home and abroad because it has the advantages of all-day and all-weather operation, miniaturization, high integration, and key sensing capabilities.
