Firstly, this paper based upon coordinate transformation in vector space, the resolution principles of ship's swinging in three rotative axes of a hull – mounted array sonar are developed. The analytical results are used as the rules to control and stabilize the attitude of the array sonar so as to isolate the swinging of the ship.

After comparing nonlinear simulation with linear, the results indicate that: Weak nonlinearity has definite and apparent influence on the distribution of acoustic fields and focused gain of array, which cause the distribution of waveform is closer to the array and the focused gain deteriorate ; the strong nonlinearity have a strong waveform aberration, because the other waves of non-fundamental frequency appear . No evident distinction is found in the effects between the oblique propagation and the vertical propagation, though less focused gain and influence caused by strong nonlinear produced by the acoustic diffraction which results in more attenuation in terms of oblique propagation.

将线性条件下的模拟结果与非线性条件下的模拟结果进行比较发现：弱非线性会对声场的分布和阵列聚焦增益产生一定的影响，使得声场分布波形比线性条件下的更加靠近阵列，聚焦效果变差；强非线性会使波形发生更严重畸变，这是由于产生了基频以外的其他频率声波引起的；非线性对斜向传播时声场分布的影响与垂直传播时的影响效果基本相同，但由于斜向辐射时的声波衍射造成的衰减要大于垂直辐射时的，因此聚焦增益和强非线性的影响都将小于垂直辐射时的情况。
