Trajectory Correction Rocket System Ballistic Kalman Filter

of filter radiation and the measure of how suppressed the Kalman filtering radiate.Because the Kalman filtering generally applies in the linear separate system,but the rocket projectile motion equations is a non-linear continuous system.Therefore the article established the trajectory filter model after carrying on linearization adopting the promoted Kalman filtering, and discretization to the equation of state and the gauging equation,as well as fetched the promoted Kalman filtering.Finally the article established the simulated program eventually.The paper compared with how the filter result under different filter parameter influenced to the filter precision,basis simulation radar surveying data analysis computation,has determined the reasonable trajectory filter parameter.
