针对确定自适应阵列系统,在传统的线性约束最小方差(LCMV)波束形成算法基础上提出一种在期望信号方向估计有误差的情况下,能减小指向误差的低旁瓣自适应波束形成算法,该算法运用波束保形函数,集中主瓣波束,抑制旁瓣波束,提高了阵列输出的信干噪比(SINR),计算机仿真结果验证了算法的有效性和优越性。 Aiming at the problem of determining the adaptive array system, a low sidelobe adaptive beamforming algorithm that can reduce the pointing error is proposed based on the traditional linear constrained least squares (LCMV) beamforming algorithm with the expected error of the signal direction estimation This algorithm uses beamforming function to focus the main lobe beam and restrain the side lobe beam and improve the signal to interference plus noise ratio (SINR) output of the array. The simulation results verify the effectiveness and superiority of the algorithm.
