A new underwater system of passive target motion analysis (TMA) is designed. The state equation and measurement equation are established and analyzed systemically by extended Kalman filter (EKF) based on the measurements of both bearings and time-delay that are collected by the two different sensors. The Monte Carlo simulation experiment results demonstrate that the algorithm has some advantages of fast convergence, high precision and stability. So the system and algorithm has a bright practice application future.
