Research Of Compound Jamming On Anti-ship Missile

The greatest threat to ships in the naval battlefield is the anti-ship missile.Disorienting anti-ship missiles by applying jamming is nowadays the most powerful scheme of protecting ships.Research on various single jamming styles has well-rounded and yielded good results in actual combats.However,with the rapid development of the anti-ship missile radar guidance system,modern guidance already can resist most of the jamming measures,and the traditional electronic jamming is acting weakly in surface ships’ protection,the research of advanced jamming style is highly required.In this thesis,in response to the poor jamming effect of traditional single jamming,the compound jamming technology for anti-ship missiles is studied based on single jamming.The implementation method of compound jamming is proposed,the construction of the compound jamming model is completed through digital modeling,and the simulation platform of the jamming effect is established.The proof of the combined jamming model’s effectiveness is achieved by designing jamming counter scenarios,which is of great significance for protecting ships against anti-ship missiles in modern naval warfare.Firstly,the combination of jamming styles is been selected according to the criteria,whether the compound jamming could cooperate with each other to enhance the overall jamming effect or make up for the shortcomings of the single jamming,and the feasibility of each possible combination of jamming is been analyzed based on the criteria.Six feasible combinations of jamming is been selected in this thesis.The six types of compound jamming are divided into two categories based on the type of jamming-"dragging and dummy target" and "suppression and dummy target",which are modeled and simulated to build a compound jamming model.Secondly,C++ is been used to model and simulate the six types of compound jamming in this thesis.In the process of modeling and simulation,a clear method is been proposed to realize the compound jamming for different states of the guidance head,and add a detailed modeling and simulation process,so that the simulated compound jamming signal has a certain degree of realism and is valuable in engineering.Finally,the verification of the compound jamming model is realized.The jamming effect simulation platform is established based on VS 2010,Qt Creator and Baidu map plug-in,and the basic module of the guidance head system is constructed,which can obtain all the functions of the guidance head system.By designing the interface,allowing the data interact between the guidance head system and the compound jamming model,a complete jamming countermeasure scenario is simulated to evaluate the compound jamming effect.Finally,the designed jamming countermeasure scenario is subjected to multiple Monte Carlo experiments to count the off-target rate,to realize the analysis and evaluation of the compound jamming effect,and to compare the jamming effect of single jamming and compound jamming,which proves the effectiveness and advantages of the compound jamming model.A viable compound jamming model is been established for ships against missiles in the naval battlefield,and a good basis for new forms of jamming styles with reference significance is been established.The problem of poor jamming effect of traditional single jamming is been addressed in this thesis,researches on the compound jamming technology for anti-ship missiles on the basis of single jamming,proposing the implementation method of compound jamming,complete the construction of compound jamming model by means of digital modeling,and establishes the simulation platform of jamming effect by designing jamming confrontation scenarios.The proof of the effectiveness of the compound jamming model is realized,which is of great significance for the protection of ships against anti-ship missiles in modern naval warfare.The core of this thesis is to built two types of compound jamming models and a simulation platform based on jamming effect conducting multiple experiments to verify the effectiveness of the compound jamming model.The jamming effect of the compound jamming model is higher than the single interference.The compound jamming is been studied systematically,establishing a good foundation for the research of new forms of jamming styles and has a certain reference significance.
