吊放声纳扇形搜索效能建模与仿真

进行潜艇搜索，在获知潜艇可疑初始位置后，其具体的航速、航向通常未知。在先验信息不足的条件下采用何种搜索方式能发现目标，以及采用该种方式的搜索效率如何，都是需要深入研究的问题。文章以双机扇形搜索为例，对直升机搜索潜艇问题进行研究。建立了水下目标位置分布模型，并利用蒙特卡洛法对搜索概率进行仿真验证，为提高搜索效率提供了参考。

Modeling and Simulation the Efficiency of the Dipping Sonar Based on Sector Searching

Search the submarine,after learning the submarine suspicious initial position,its concrete speed and direction usual unknow.The problems we need to study are that in conditions of lack of prior information,which methods adopted could we find the target,and how the efficiency of this method.This article takes the sector searching as an example,researching the helicopter search the submarine,establishing the submarine target poisition distrbution model,and using the Monte-Carlo method simulation validation fo...
