Research On The Technology Of Attack-defense Of Anti-ship Missile

Anti- ship missiles become more and more important in the current offensive and defensive confrontation. And the defense system is also developed because of developing of anti- ship missiles. Therefore, it is significant to carry out a thorough study on offensive and defensive confrontation. This paper establishes a model of anti-ship missile as the offence and models of short-range naval gun and ship to air missile model as the defense, combining them to establish a model of attack and defense confrontation and study its performance.Firstly, considering the model of error of system, the model of spreading, the model of judgment and other models, establish the model of Phalanx Close-In Weapon System. Establish the particle motion model of anti-ship missile with different kinds of maneuvers. Then establish the offensive and defensive confrontation with the simple model of anti-ship missile and the model of Phalanx Close-In Weapon System, and use the Kalman filtering algorithm to estimate the motion information. Simulate and study on the blocking probability of the model of defense with different penetration strategies of anti-ship missile.Secondly, establish an accurate model of six degree of freedom, and use automatic control theory to design overload autopilot. Design typical maneuvering of anti-ship missile, such as snake maneuvering, leap maneuvering and sea skimming. Study and simulate on the six degree of freedom trajectory of anti ship missile with different typical maneuvering. Establish the model of ship to air missile as the defense model. Then establish the offensive and defensive confrontation with the accurate model of six degree of freedom of anti-ship missile and the model of ship to air missile. Study on the influence of different performance of autopilot and conditions of maneuver on the offensive and defensive confrontation with Monte Carlo method. Considering random factors, simulate with Monte Carlo method, and analysis the hitting probability of ship to air missile.Finally, considering search segments of anti- ship missile in practical engineering, improve the design of one-dimension visual effect. Considering two order character and coupling model of seeker, based on the idea of segmentation and symmetry, the transition process of the search law of one-dimension visual effect is improved. Simulation results show that the improved search law improves the performance of tracking of seeker.
