反潜巡逻机应召布放多基地声纳阵搜潜效能研究

Efficiency Research for On-call Anti-submarine by Anti-submarine Patrol Aircraft Dropping Multistatic Sonar Array

为提高反潜巡逻机传统应召搜潜效能,提出采用反潜巡逻机应召布放多基地声纳阵的方法。在传统方法的基础上,根据已知的潜艇信息,利用多基地声纳的优势建立反潜巡逻机应召布放圆形、方形、三角形多基地声纳浮标阵搜潜模型,依据声波衰减原理,通过Matlab仿真初始距离,潜艇初始概略分布、潜艇经济航速、布放半径和被动浮标布放个数对各方案搜潜效能的影响。仿真结果表明:3种多基地阵方案的搜潜效能随着初始距离、初始概略位置分布、潜艇经济航速的增大而减小。在相同条件下,圆形多基地阵的搜潜效能最佳,且相比同样基于传统方法的圆形被动浮标阵搜潜效能提高明显,并能根据实际情况选择合适的布放半径和被动浮标布放个数。该方法适用于反潜巡逻机应召搜潜,对反潜作战具有一定的军事意义。
