摘要
An adaptive multiple-input multiple-output (MIMO) radar beamforming technique based on direct data domain (D-3) approach is presented. The proposed method generally outperforms traditional adaptive beamformers in surprise or rapidly changing interference scenarios due to the use of a D-3 interference cancellation technique, which utilises a single snapshot for adaptive beamforming. The proposed D-3 approach suffers from performance degradation in the presence of uncertainty in the knowledge of target direction. To overcome this problem, a robust D-3 approach using worst-case performance optimisation is developed to achieve robustness against look direction error.
