Multi-target detection algorithm for FMCW radar

by Hyun et al.
The authors conduct research on multi-target detection algorithms. In their abstract, they state that “FMCW (Frequency Modulation Continuous Wave) radar has been a popular method for automotive applications. The typical FMCW radar, however, has serious problems in multi-target situations. That is, range-velocity processing gives rise to so-called ghost targets due to Doppler shift in the received beat-frequency. In this paper, we propose a new transmit wave and detection algorithm. In the proposed method, the rough range is detected in the first period, and the fine range and velocity are obtained in the second period.”
