Abstract: For the contradiction between the model accuracy and the tracking model dimension in the ship electric field tracking, the influences of point charge number and the depth of observation point on the accuracy of model are analyzed and the minimum requirement for point charge number on the corresponding depth plane is defined based on the ship electric field point charge array model and the ship electric field inversion algorithm. In the analysis, the dimension of tracking filter is reduced while ensuring the modeling accuracy and the stability of filtering algorithm.A progressive update extended Kalman filter (PUEKF) was designed for the simulation analysis and experimental verification of ship electric field tracking. The results show that a electric field model with a small number of point charges can be used to replace the complex ship electric field point charge array model in ship electric field tracking, which has high tracking accuracy. The PUEKF can effectively improve the initial error tolerance range and has high filtering stability. The tracking error is less than 10m in the range of 500 m. The PUEKF has low computational cost, which is suitable for engineering applications for the ship electric field tracking. Key
