Research On Key Techniques Of Offensive And Defensive Warfare Against Air Sea Missiles

In recent years,large-scale naval exercises have been carried out frequently in various countries.Maritime exercises include simulated attackers and defenders,and take anti-ship missiles and ship-to-air missiles as the main drilling weapons to conduct offensive and defensive confrontation.Practical drilling requires a lot of material,human and financial resources,which is an extremely complex project.But military exercises also bring a lot of benefits,such as showing their strength to other countries and accumulating valuable experience for their own operations.The United States is arrogant in the world by virtue of the "invincible fleet",which may better explain the significance of maritime combat status.More countries call the ocean "blue land." In view of the increasingly frequent maritime disputes,it is necessary to conduct in-depth research on the Offensive-Defensive confrontation between the two sides of the maritime operations,especially the Offensive-Defensive confrontation of anti-ship missiles and ship-to-air missiles.In this paper,the typical operational process of anti-ship missile and ship to air missile attack defense confrontation is designed,and the main antagonistic weapon models are established: anti-ship missile model and ship to air missile model,and some key technologies in the process of missile attack defense confrontation are studied.The main contents of the paper are as follows:1.Typical operational process design of missile attack-defense confrontation.For naval operations,this paper designs typical operational processes of airborne anti-ship missiles and ship-borne anti-aircraft missiles.The motion models of air targets and sea targets are established respectively,and a missile’s three degree of freedom model is established.A typical missile flight trajectory is designed and simulated.In the terminal maneuver strategy of the anti-ship missile,the trajectory simulation of snake,vertical snake,helix,pendulum and jump maneuver is carried out through integrated control,which proves the feasibility of the typical operational process and model.2.Missile attack defense confrontation process simulation.In view of some key technologies in the process of missile attack and defense,the specific steps are as follows: in order to further improve the calculation speed,the dual variable step size is adapted to the dynamic adjustment time and distance step length in the fire control calculation,and the missile escape area is simulated and solved.Finally,Monte Carlo method is used to compare the penetration probability of different maneuvering anti-ship missiles against ship to air missiles.3.Effectiveness evaluation.Aiming at the operational effectiveness of anti-ship missiles,the concept of support degree S is introduced on the basis of traditional ADC method.In actual confrontation scenarios,considering the existence of countermeasures,the operational effectiveness of missiles is divided into two parts: basic operational effectiveness and confrontation operational effectiveness,and the effectiveness calculation system is established.
