Based on kalman filter theory multiple launch rocket ballistic parameters filtrating analyze

For the dynamics system of multiple launch rocket s, measuring error of ballistic parameters will appear under the influence of noise disturbance signals. The method of filtrating and estimating the ballistic parameters in the flight of multiple launch rocket is putted forward based on the theory of Kalman filter in this paper. And a filtrating example is also demonstrated in order to get more precise ballistic parameters of rocket with the aim of increasing firing accuracy of the rocket.
