The Research Of Efficient Method For Firing Data Calculation Of Ballistic Missiles In Mobile Condition

The main purpose of this thesis is to investigate an fast method for firing data calculation of ballistic missiles and do the best to make a contribution to solving the Real-time calculation problem of firing data for certain model missile.First of all, the thesis investigates the fast trajectory calculation techniques for standard trajectory. For power-flight standard trajectory, the stage one-stage two ballistic fitting method under constant flight program and the stage three ballistic analytic method are adapted. And the stage three ballistic analytic method under the variational trust and the variational fuel consumption ratio is advance further. For reentry-flight standard trajectory, the thesis gets the one rank velocity, the one rank velocity obliquity, the fight time and range of the reentry trajectory, on the base of some assumption which is closed to the true condition.The thesis analyses the fast trajectory calculation techniques for warp trajectory, considering gravity anomaly and positioning and orientation deviation. For gravity anomaly calculation, the thesis applies extension approximate method in power-flight trajectory, and applies pole changing spherical harmonics method in unpower-flight trajectory, and gains the balance between the precision and the memory.The thesis provides a novel project for firing data calculation of ballistic missiles. For basic firing data calculation, the thesis applies the two-stage method, which makes the result approach the precision demand quickly by applying the trajectory analytic solution, and effectively reduce the times of the integral iterative. For correct firing data, the thesis provides three projects, and which one to be chosen is determined by the practice demand in application. Finally the advantage of this solution is proven by simulated computing.
