摘　　要：对合成孔径声呐的运动误差进行了三维建模,分析了X,Y,Z方向3种位置误差对斜距的影响;给出了基于运动参数估计的运动补偿方法,并对侧摆误差模型进行了计算机仿真,仿真结果表明该方法有效地补偿了包络及相位误差,提高了成像质量。In this paper, a three-dimensional motion error model of synthetic aperture sonar is constructed and the influence of motion error on range is analyzed. A new motion compensation method based on motion parameters estimation is presented in this paper. Computer simulations for sway error based on the derived model are given in the end of this paper. The simulating results show that the proposed motion compensation method compensates the envelope error and phase error effectively and the imaging quality is improved.
