Abstract


According to a predetermined trajectory,ballistic missile with rocket engine propulsion takes a flight to intended targets under the action of the control system. This paper aiming at some ballistic missile, calculates on its trajectory and analyzes various error sources that effect the accuracy of a missile attack.This paper first analyzes the force and state motion of the missile in flight, establishes the differential equations of ballistic missile .The earth reference model and standard atmosphere model are given. Carry out on the six degrees freedom simulation of full trajectory to simulate the actual process of missile launch. Have a research about the method of data calculation in standard trajectory. Design the computer simulation program of the ballistic flight, analyze changes of different parameters of missiles in flight. In addition, analyze the accuracy impact of the missile by error sources such as inertial measurement unit instrument error, vertical deviation and other interfering factors; Give distance result from different error sources by simulating the shooting or the Monte Carlo analysis.The results provide the basis for the missile semi-physical simulation, and have the guiding significance for selectively reduce the error on the source of the error, thereby reduce the missile guidance accuracy error.
