The Applied Research Of Adaptive Random Shift FH In Artillery Communication

With the continuous deepening of the reform of the armed forces,high technology has become the trend of the development of military equipment,artillery forces due to shoulder the firepower to combat missions,the communication is particularly prominent.The purpose of this paper is to study the technical characteristics and performance of the existing communication equipment of artillery,and to improve the communication ability of the artillery by adding the variable frequency hopping frequency hopping adaptive system.Due to the complex battlefield electromagnetic environment,means of communication jamming constantly enriching and developing,natural disturbance and human disturbance together add to the complexity and variability of artillery communication environment,this paper the problems and insufficiency of artillery communication,present concerns and give the solution.Combined with the artillery group communication using frequency hopping technology,frequency hopping communication system model was built,and using the Matlab/simulink platform to build the frequency hopping communication system simulation,and attack on the system with the main interferences,with interference suppression,interference factor and other indicators to assess,and found that the frequency hopping system subjected to the interference of communication exist the shortcomings and loopholes,jumping by changing the speed,improve artillery group communication ability.Including anti jamming and interference processing delay,interval frequency hopping technology index is proposed in frequency hopping communication system based on,adding tracking interference generation module,hopping rate initialization module,jump speed control module and data simulation observation module construct jump speed adaptive frequency hopping communication system model.Using the tracking jamming to attack the hopping speed adaptive frequency hopping system,using the factors that are delayed by the time limit of the jamming,the anti-jamming ability is improved by the method of reducing the frequency residence time.
