直升机单机等距螺旋应召搜潜效能模型与仿真

等距螺旋法是直升机应召反潜中常用的搜潜样式。潜艇位置误差及航速误差对螺旋搜潜概率及搜潜战术运用具有显著影响。依据研究问题的逻辑关系,分别建立了潜艇速度散布模型和等距螺旋搜潜效能模型,运用蒙特卡罗法对直升机应召螺旋搜潜效能进行分析评估。实例验证了模型的可信度,提出了存在潜艇速度误差条件下,延迟时间和预估航速的改变对于搜潜效能的影响。

Model and Simulation of Logarithm Spiral On-called Antisubmarine Searching by Single Helicopter

Logarithm spiral has been an usual way in on-called searching. Searching effects and Searching tactics application have been influenced by the errors of location and speed of submarine. The models of speed and location distribution have been built by logical relationship of research questions. The effects of helicopter on-called searching has been assessed and analyzed by monte carlo. Realiability confidence levels has been checked by examples. The influences of searching effects have been changed by delayed time and estimated speed with the existence of speed error.
