线导鱼雷靶场散布分析

Analysis of Shooting Range Scatter for Wire-guided Torpedo

在线导鱼雷实施导引过程中应充分考虑鱼雷靶场散布范围的大小,以确保鱼雷能进入对目标实施有效自导的区域内。基于平台作战仿真、装备作战效能评估和武器作战使用方法研究等应用的需要,考虑到鱼雷制导方式的差异,分析了线导鱼雷导引过程中造成鱼雷散布的原因。鱼雷位置散布可分为鱼雷靶场散布和舰艇散布,其中前者是引起鱼雷位置散布的主要因素。该文给出了鱼雷靶场散布的数学模型,计算了鱼雷航程误差、鱼雷横向误差和鱼雷深度误差的范围,并以鱼雷的平均位置为中心,以深度误差为厚度,以航程误差和横向误差为长短半轴,得到了线导鱼雷导引过程中鱼雷位置散布范围为一扁平椭圆体的结论。

The scope of shooting range scatter should be considered in the guidance process of wire-guided torpedo to ensure it entering into the area, where torpedo can implement effective homing to target. Based on the needs for the simulation of operation platform, operational effectiveness evaluation for equipment, and development of weapon operational method, this paper analyses the reasons why the scatter of wire-guided torpedo happens with a consideration of different control and guidance modes. The position scatter can be divided into the shooting range scatter and the ship scatter and the former is primary. Therefore, some mathematical models in three aspects of shooting range scatter are established, and the error scopes of range, horizon and depth are calculated. According to the above results, it is concluded that the scope of position scatter in the guidance process of wire-guided torpedo is a fiat elliptical sphere.
