【Abstract】 The forming filter of stochastic sea interference is designed and realized based on the method of least squares step by step in this paper. The effect of colored Kalman filtering is compared with extended Kalman filtering (EKF). By using the forming filter and EKF, the precision of states estimation is increased and a effective estimation of stochastic sea interference is performed. Simulation result shows that the estimation of stochastic sea interference obtained by EKF is feasible.更多还原
