基于反潜直升机平台的吊放声呐与浮标多基地模式应召搜潜概率仿真研究

Research on the Probability Simulation of Lifting Sonar and Buoy Based on Anti-Submarine Helicopter Platform

针对反潜直升机单机单设备搜潜能力不足的问题,提出双机使用吊放声呐与声呐浮标进行协同多基地搜索的方案,分析了吊放声呐-浮标双/多基地作用机理及扩展面积相关问题。在改变目标潜艇速度、应召延迟时间与直升机携带浮标个数三个条件的情况下,仿真了三角形、方形与圆形三种常见双机协同搜索模型采用多基地方案后给搜潜效果带来的影响。仿真结果表明,搜潜概率与应召延迟时间目标潜艇速度负相关,与直升机携带浮标数正相关;由于多基地系统可以显著提高搜索面积,相同条件下采用吊放声呐与声呐浮标多基地搜索模式相比于单基地具有一定优势。

Aiming at the problem that single aircraft and single equipment of anti-submarine helicopter has insufficient ability to search for submarine,a method of joint multi-base search using sonobuoy and lifting sonar is proposed,and the bistatic/multi-base action mechanism of lifting sonar and buoy and the related problems of expansion area are analyzed.Under the condition of changing the speed of target submarine,the call delay time and the number of buoys carried by helicopter,the influences of three dual aircraft cooperative search models of triangle,square and circle on the submarine search efficiency are simulated.The simulation results show that the probability of submarine search is negatively correlated with the target submarine velocity of the response delay time and positively correlated with the number of buoys carried by the helicopter.Because the multi-base system can significantly improve the search area,the multi-base search mode of lifting sonar and sonobuoy has certain advantages over that of single base under the same condition.The research results have certain guiding significance for the practical use of anti-submarine helicopter.
