摘要
针对水下被动目标跟踪的非高斯噪声环境和弱可观性的特点,提出了将粒子滤波算法应用于水下被动目标跟踪中的非线性问题,克服了常规的线性化方法易发散且跟踪精度低、误差大的缺点.仿真结果表明:粒子滤波算法提高了滤波的稳定性,跟踪精度优于扩展卡尔曼滤波算法和无迹卡尔曼滤波算法,收到了良好的效果,具有较高的实用价值.
Considering the nonlinear non-Gaussian and weak observation of the underwater target passive tracking,the particle filter algorithm was studied and used to the problems in this paper.The proposed algorithm could overcome the conventional linear methods′shortcomings,such as easy divergence,low tracking accuracy,and large error.Simulation results show that the particle filter can enhance the stability of the filtering,and its tracking accuracy is better than EKF and UKF algorithms.
