中文摘要:
      阵形估计是拖曳阵声呐在拖船转向机动情况下不能回避的问题。已知的Water-Pulley(WP)模型所需信息易于获取,运算复杂度小并且可以预判阵形,在工程实际中有一定应用价值。但WP模型稳健性有限,阵形估计效果受拖船机动情况影响较大。为探究WP模型适用性以指导拖船机动避免模型失效,首先通过计算机仿真证明拖船转弯半径是最主要的影响因素;然后提出一种以最大测向误差和最大增益损失为模型适用准则,结合某船旋回特性以指导拖船机动的方法;最后分析了存在水流扰动时应注意的拖船机动情况。
英文摘要:
      Array shape estimation of towed array sonar is an important problem that cannot be ignored during ship's maneuvering. The existing water-pulley model (called WP model) has certain application value due to easily obtaining required information, less computational complexity and being able to predict the array shape. But, the robustness of the WP model is limited. Ship's maneuvering has great impact on array shape estimation. In order to explore the applicability of the model to guide ship's maneuvering and to avoid the model failure, the paper firstly makes simulation to prove that the turning radius is the most important factor, and then proposes a method to guide ship's maneuvering according to the model applicable criterion of maximum direction error and maximum gain loss. Finally the effect of flow disturbance on ship's maneuvering is analyzed.
