Research And Simulation Of Several Strategies For Missile Penetration

In the modern war, strategic deterrent of all kinds of missile is very powerful and it may determine the military strength of a country to some extent. Penetration technology is an important means to improve the survivability and battle capacity of missiles, ant it has become the basic design element of a new generation of missile. The application of penetration technology has been widely used and missile penetration ability has been greatly improved to pursue penetration effect on the current stage. Overall, proposing new ideas or innovation of penetration strategy will be more conducive to the future development of missile in our country. In accordance with the requirements of missile penetration, several penetration strategies have been studied and simulated for a single missile and multiple missiles in this paper. Main work includes:In the first part, the purpose and significance of research is introduced and a brief overview of penetration technology is related. The missile penetration problem is descripted in in mathematical form. According to the characteristics of ballistic missile, mathematical models of the missile in active phase, free flight phase and reentry phase is built under the ideal assumption of physical conditions and flight environment. The mathematical model of frigate missile is built finally for the following use.。In the second part, penetration strategies of a single missile are designed by two different methods. First, the missile with baits and guard missile is put forward and the head pursuit guidance law is designed and used by guard missile. Then the optimization method of jump-like ballistic is given. Through optimizing of static parameters and designing of guidance law, the optimal jump-like flight trajectory has been got and the penetration ability of missile has been improved.In the third part, the penetration strategy of multiple near-space hypersonic missiles is designed. Considering the constraint conditions such as flight mission points and flight threat areas, the combination algorithm of direct method and indirect method is adopted which is combination algorithm of the improved dynamic programming method and conjugate gradient method to optimize the trajectories of multiple near-space hypersonic missiles in complex flight environment. A large number of flight simulation results show that the penetration strategies above can get a satisfactory effect.
