基于柔性阵的鱼雷攻击部位定位

Localization of torpedo attack position based on a flexible hydrophone array

鱼雷不同的攻击部位攻击效能差别较大,为了检验鱼雷攻击效能,需要对鱼雷的攻击部位进行定位,结合海上测量环境和水面舰船的尺寸特点,分析了船舷布放柔性阵进行鱼雷攻击部位定位的定位性能,提出了一种基于六元柔性阵的鱼雷攻击部位定位的方法.通过计算机仿真,分析了阵元校阵精度、时延估计精度和阵元个数及阵型对柔性阵三维定位精度的影响,结果表明,利用六元柔性阵,可以达到鱼雷命中部位测量所需的精度要求.

The torpedo has different effectiveness while attacking different area. In order to evaluate the effectiveness, a torpedo attack position needs to be located. Considering the characteristics of the measurement environment at sea and ship size, localization performance of the torpedo attack position is analyzed by a flexible hydrophone array. A new method is presented based on a six-element flexible hydrophone array, the affection of the precision of sensor array,and delay estimation,and array elements and formation on three-dimensional location accuracy are analyzed by computer simulation. Simulation results show that the six-element flexible hydrophone array can satisfy the accuracy requirement in the measure of a torpedo attack position.
