摘要： 针对航空反潜中使用空投被动声纳浮标对潜艇进行跟踪的问题，利用双曲线交汇法定位，研究被动浮标对水下目标进行连续跟踪的方法，建立相应数学模型。仿真结果证明了该方法的可行性，得到目标的航速、航向、运动状态变化间隔、声纳浮标位置等因素变化与跟踪所需声纳浮标数量的关系。

Abstract: Aiming at the actual problem in aerial anti-submarine war by passive sonobuoy, this paper uses hyperbola intersection method to position, researches how to continuously track underwater target by means of passive sonobuoy, and builds corresponding mathematical model. Simulation results prove the feasibility of this tracking method, and gets the relation between the number of sonobuoys needed and velocity, course, interval of shifting state of target and position of sonobuoy.

Key words: hyperbola intersection method, passive sonobuoy, underwater target, tracking
