The antisubmarine aircraft use passive omni-directional sonobuoys to track the submarine can be hidden, but the consumption of sonobuoys is large. On condition that positioning accuracy is valid, how to optimize deployment of sonobuoys in order to effectively increase the tracking time is a important problem. The detection performance of buoys and positioning accuracy are firstly analyzed, getting five basic principles of sonobuoys deployment, and then underwater target tracking technology is simply summarized. On these basis, Two optimization methods of deploying sonobuoys for submarine tracking are proposed: one is based on simple genetic algorithm, the other is based on simple translation of multi-dimensional optimization into one-dimensional optimization for multi-parameter buoys group. Finally, tracking performance and the buoy consumption of the two methods are simulated, the results show that they can meet the tracking requirements, and the former require fewer buoys, but the latter need fewer batches, which can reduce the workload.%反潜飞机利用被动全向声纳浮标可以隐蔽地跟踪潜艇,但浮标消耗量大.在满足定位精度的条件下,如何优化布放浮标以便有效增加跟踪时间是一个亟待解决的问题.首先分析了浮标探测性能和浮标群相对位置对定位精度的影响,得到浮标布放的五种基本原则；然后结合水下目标跟踪技术提出了两种用被动全向声纳浮标跟踪潜艇的优化布放方法:一种是利用遗传算法来优化每一枚浮标的布放位置,另一种是将一批次投放2-4枚浮标的多维优化问题简单转换成一维优化问题来确定浮标的布放位置.最后仿真计算了这两种方法的跟踪性能及浮标消耗量.仿真结果表明,两种优化布放方法均能满足跟踪要求,前者的浮标消耗量比后者略少,但后者的投放批次少很多,有利于减少人员的工作量.
