摘要:

针对复杂噪声条件下传统闭式解算法和部分优化算法在进行多基地声纳目标定位时定位精度和稳定性不足的问题,引入差分进化算法求解定位模型。通过解析信号传输路径的几何关系,建立基于到达时间差的双曲定位模型,并详细阐述差分进化算法求解定位模型的核心思路与数学过程。利用仿真实验,确定适用于不同噪声水平的差分进化算法关键参数;验证在传感器位置、声速、时延测量误差的噪声条件下相较于模拟退火算法和牛顿迭代算法,该算法具备更优的定位性能;并研究定位误差的空间分布特性,尽管从传感器网络的几何中心向外,该算法的定位精度逐渐降低,但仍能实现对目标的有效定位。研究成果证明了差分进化算法在多基地声纳系统中进行目标定位的可行性和鲁棒性。

Abstract:

To address the insufficient localization accuracy and stability of traditional closed-form solutions and part optimization algorithms in multi-static sonar target localization with complex noise conditions, the differential evolution (DE) algorithm is employed in this study to solve the localization model. By analyzing the geometric relationships of signal transmission paths, a hyperbolic localization model based on time difference of arrival is established, and the core idea and mathematical procedures of solving the localization model using the DE algorithm are elaborated in detail. Simulation experiments are conducted to determine the key DE algorithm parameters suitable for various noise levels. The results validate that with conditions involving sensor-position, sound-speed, and time-delay measurement errors, the DE algorithm achieves superior localization performance compared to both the simulated annealing algorithm and the Newton iteration method. Moreover, the spatial distribution characteristics of localization errors are investigated. Although the localization accuracy gradually decreases with increasing distance from the geometric center of the sensor network, the algorithm remains effective in achieving target localization. The research demonstrates the feasibility and robustness of applying the DE algorithm for target localization in multi-static sonar systems.
