Research On High Power Microwave Crisis Communication Technology

As the electromagnetic environment of the battlefield becomes increasingly complex and deteriorating,the battlefield communication system may be disturbed and destroyed by the enemy.Emergency communication as an important part of the battlefield communication system,refers to the communication respond to emergencies.on the military.When conventional means of communication are facing interfered or destroyed by enemy.The communication was interrupted.So that emergency communication is required to guarantee a basic communication.Therefore,emergency communication should have the characteristics of strong anti-damage ability,quick maneuvering or opening,strong anti-interference ability and so on.High power microwave signal has high peak power,low repetition frequency of pulse,short pulse and concentrated pulse energy.If it can be used in emergency communication,it can effectively improve the anti-interference ability and communication distance of communication.In recent years,with the rapid development of high power microwave,its application in military field is more and more extensive.High power microwave source multiplexing is precisely based on this.The high power microwave source should be applied to detect,interference,detection,directed energy weapons and even communication's power source.This dissertation takes the application of high power microwave communication as the research background.The characteristics of high power microwave signal are analyzed.According to the requirement of emergency communication,it is the first attempt to apply high power microwave signal to communication.It adopts pulse width modulation,which is suitable for high power microwave signal characteristics.The advantages of high power microwave signal in emergency communication are briefly analyzed.The anti-interference performance of high power microwave emergency communication system is analyzed by MATLAB simulation experiment.The simulation results show that the application of high power microwave signal to communication can effectively improve the anti-interference ability of communication system,and demonstrate the feasibility of applying high power microwave to emergency communication.Finally,through the demonstration experiment,it has realized the function of using high power microwave for simple communication.
