| Abstract: |
| There is a problem at the end of the trajectory of ballistic missile which is the optimal guidance law of breaking through the defense system.For that problem, we could analyze different guidance laws by using the multiple stage analyzing theory.As we analyze the means and variances of the precision, the maximum of the overload, the flight time and the precision of the anti missile, we can assess the performance and importance of the guidance laws.And then, we set up reasonable parameters of the analyzing theory.And after random simulation, we will get the score of different guidance laws by using it.The result of simulation proves that the AHP can be used in choosing and optimizing guidance law at the end trajectory of ballistic missile |
| Key words: Ballistic missile Guidance law Multiple stage analyzing theory |
