拖线阵保持对目标有效接触的机动时机选择方法

Maneuver timing selection method for towed linear array to maintain effective contact with target

为研究通过拖船机动保持拖线阵对目标有效接触中的机动时机选择问题,首先基于Paidoussis方程和偏微分方程特征线理论求解拖点扰动的影响区域,得到零浮力缆上各点对于拖点机动的响应时间;然后,在Paidoussis方程中代入尾端形阻系数及调整后的阻力系数,得到描述拖缆段运动状态的方程,并将求解响应时间的方法应用于拖线阵;最后,计算目标运动到有效观测区间临界角度的时间,进而提出拖船机动时机的选择方法,使得持续接触目标过程中机动次数尽量少。仿真结果验证了该方法的有效性和可行性。

To study the maneuver timing selection method for the towed linear array to maintain effective contact with the target by the tug maneuvering,firstly,based on the Paidoussis equation and the characteristic line of partial differential equations,the affected area of the drag point disturbance was obtained,and thus the response time of neutrally buoyant array for tow point maneuvering was obtained.Then,the drag coefficient for the drogue at the end of the cable and the adjusted drag coefficient were substituted in the Paidoussis equation to obtain the equation describing the motion of the cable.The method of solving response time was applied to the towed linear array.Finally,the time of target to move to the critical angle of the effective observation interval was calculated,and then the maneuver timing selection method of the tug was proposed,so that in the process of continuous contact with the target the number of maneuvers was as small as possible.The simulation results verified the effectiveness and fesibility of the proposed method.
