提出了一种基于特征投影算法和波束相似性约束的主瓣干扰抑制新方法。该方法能有效地抑制多主瓣干扰和多副瓣干扰。自适应波束形成的输出是由凸目标函数得到的自适应权向量和基于特征投影矩阵的处理后的回波数据计算的。仿真结果验证了理论分析的正确性。
Here a novel mainlobe interference suppression technique based on eigenprojection algorithm and beam pattern similarity constraints is proposed. This method can effectively suppress the multiple mainlobe interferences and sidelobe interferences. The output of adaptive beamforming is calculated via adaptive weight vector obtained by the convex objective function and processed echo data based on the eigenprojection matrix. The simulations have been presented to evaluate the theoretical analysis.
