The research of underwater passive TMA algorithm with bearings and frequencies measurements
Xuan Zhao-lin · Ship Science and Technology · 2006
Base on the measurement of both bearings and frequencies by passive observer,the linear equation of both state and measurement are established through pseudolinear method applied to innovation and the modified extend Kalman filter is obtained and can be estimate the parameters of moving target.The Monte-Carlo simulation experiment results demonstrate that the MEKF algorithm has some merits of fast convergence,high precision and stability.So the algorithm can be applied to the long-range underwater passive TMA.
