Abstract: An approach for estimation to states of missile guidance based on predictive filtering is derived for the measurement process with high and low frequency noise. Analyze the influence of various noises on miss distance. Comparing with the extended Kalman filter, the simulation results indicate that this new method is able to improve accuracy of the guidance system with less estimation error.

Abstract: A new type of guidance law is developed for intercepting high maneuvering target. The law takes angular acceleration of line-of-sight as a primary input in place of the acceleration of target. As the significant required input quantity of the angular acceleration guidance (AAG), the angular acceleration of line-of-sight is estimated by a developed estimation approach based on sliding mode observer (SMO). Simulation results demonstrates advantages of this AAG guidance with the estimation approach based on SMO by comparing with the conventional guidance techniques and extended Kalman filter.
