A rapid method for flight program design of the ballistic missile launched on mobile platform

Abstract:

Combining analytical prediction and optimization of parameters, a rapid method for basic firing data of flight program of the ballistic missile launched on mobile platform is studied. First, the analytical expressions between the parameters about flight program and attack information are obtained by using polynomial function approximation, by which the initial value of the firing data can be calculated. Second, considering the parameters of flight program as variables and the least square of the placement's aberration as the performance index, the Levenberg-Marquardt (L-M) Method is used to obtain the optimal values. Finally, as an example, the proposed method is provided to attacking targets with the LMG-30G. The simulation results show that, because of the less computational effort, the proposed method is suitable for the rapid design of the Big Wide Intratheater Mobility for the missile. When the precision of the placement is not highly demanded, the solution of analytical expressions can be used directly as the value of flight parameters to attack the target.
