Research on simulation and technique of parameters estimation based on target movement of line deflection measurement

Target kinematics and measurement equations of a remote control guidance system were proposed. In order to estimate parameters of target movement, an extended Kalman filter and an adaptive extended Kalman filter used for non-linear measurement model and linear dynamic model were proposed. Numerical simulation shows that the performance of an adaptive extended Kalman filter is better than an extended Kalman filter in estimation of target moving parameters of guidance systems.
