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 differentiating the Empty-band of two adjacent frames. Simulation experiments show that this method can effectively solve the interference problems arising from Empty-band demodulation, and has certain practical significance.
