Abstract:High-Performance Automotive Millimeter-Wave Radar usually uses Doppler Division Multiple Access (DDMA) to build virtual MIMO arrays. However, the DDMA approach leads to blurring of the radar velocity interval and severe antenna interference problems. In this paper, we analyze these two problems in the DDMA mode, and also propose an improved DDMA target demodulation method, which can efficiently identify the interference target and correctly estimate the velocity of the interference target by means of different… Show more
