摘　　要：RLS算法作为一种自适应波束形成算法,以其算法简单有效而得到广泛的应用。分析了多径传播环境下,不同信号方向的方向图及功率,SNR变化对自适应波束形成算法性能的影响。将RLS-LCMV自适应算法用于水声传感器阵列信号的波束形成,完成了在线性约束最小方差(LCMV)下波束形成的仿真。该算法具有收敛速度快,抗扰动性强的特点。RLS algorithm as one of the adaptive beamforming algorithms is widely applied. The directional diagram and power of different signal directions in the environment of multipath propagation are analyzed, and the impact of variational SNR on the adaptive beamforming algorithm is discussed. The beamforming of underwater sensor array signal was implemented by the RLS-LCMV adaptive algorithm, and the simulation of linearly constrained minirrnum variance beamforming was completed. The algorithm has fast convergence rate and resistance of disturbance.
