Abstract: For the array mounted on high-speed platform, the performance of conventional adaptive beamforming algorithm can be seriously degraded, due to the presence of fast changing of interference direction and look direction error. To combat the impact, a robust beamforming method based on interference location prediction is proposed. First, we define the normalized spatial frequency and predict the range of the interference location. Then, a robust adaptive beamformer is derived by a matrix weighted approach, which can suppress the gain in the predicted region and maintain the gain in the mainlobe region. Therefore, the proposed method is more robust to interferences and look direction errors. Simulation results demonstrate the effectiveness of the proposed method.
