摘　　要：针对目前常用的声定位系统在浅水区因受各种环境噪声影响而使搜潜效果较差的情况,提出了一种新的水下潜艇磁性定位追踪方法。该方法利用潜艇磁场的衰减特性构造了一种多目标规划的目标函数,通过微分进化算法与方向加速法相结合的优化算法,确定使目标函数最优的定位追踪参数。实验证明,所提出的方法仅需已知3个磁传感器所测潜艇磁场的一部分,就能较准确地确定潜艇的航行深度h、航速v及磁航向角φ这些重要追踪参数,并能对潜艇长度及位置进行有效的估计,计算结果稳定可靠,不依赖于初始值的估计精度。Aimed at the effects of detecting submarine is not satisfied based on the sonar system on the littoral zones,a new submarine localization and tracking method is presented.The method constructed a new objective function on the basis of the attenuation characteristic of submarine＇s magnetic field, and applied the combination of differential evolution algorithm and Powell algorithm to find the optimum of the objective function.By means of ship＇s model experiments,it was demonstrated that the new localization method could utilize a part of the magnetic field measured by three selected sensors to identify vessel＇s track, speed,and course relative to the sensors with high numerical precision,and the length of the submarine could be acquired.The localization results proved the effectiveness of the proposed method and its potential application value of researching the magnetic signature of the diving submarine.
