针对由于取样协方差矩阵估计误差和导向矢量扰动误差的存在，使波束形成器产生高的旁瓣和畸变的主波束，提出了用代价函数校正导向矢量扰动误差引起的方向图畸变．当两种误差同时存在且为非白色高斯扰动时，可用联合处理法来校正方向图畸变．计算机仿真结果表明，这种校正方法是有效的． Aiming at the problem that the beamformer generates high side lobe and distorted main beam due to the estimation error of sampling covariance matrix and disturbance of steering vector, this paper proposes a price function to correct the distortion of the pattern caused by the disturbance of the steering vector. When both errors exist at the same time and are non-white Gaussian perturbations, a joint approach can be used to correct the pattern distortions. Computer simulation results show that this method is effective.
